+==========================================================
+CMSIS defines for a Cortex-M Microcontroller System:
+
+ * A common way to access peripheral registers and a
+ common way to define exception vectors.
+ * The register names of the Core Peripherals and the
+ names of the Core Exception Vectors.
+ * An device independent interface for RTOS Kernels
+ including a debug channel.
+
+By using CMSIS compliant software components, the user can
+easier re-use template code. CMSIS is intended to enable the
+combination of software components from multiple middleware
+vendors.
+
+This project contains appropriate files for this MCU family
+taken from CMSIS. A full copy of the CMSIS files can be found
+within your tools installation directory. More information on
+CMSIS can be found at:

+<h1>Changes to CMSIS version V1.20</h1>
+
+<hr>
+
+<h2>1. Removed CMSIS Middelware packages</h2>
+<p>
+ CMSIS Middleware is on hold from ARM side until a agreement between all CMSIS partners is found.
+</p>
+
+<h2>2. SystemFrequency renamed to SystemCoreClock</h2>
+<p>
+ The variable name <strong>SystemCoreClock</strong> is more precise than <strong>SystemFrequency</strong>
+ because the variable holds the clock value at which the core is running.
+</p>
+
+<h2>3. Changed startup concept</h2>
+<p>
+ The old startup concept (calling SystemInit_ExtMemCtl from startup file and calling SystemInit
+ from main) has the weakness that it does not work for controllers which need a already
+ configuerd clock system to configure the external memory controller.
+</p>
+
+<h3>Changed startup concept</h3>
+<ul>
+ <li>
+ SystemInit() is called from startup file before <strong>premain</strong>.
+ </li>
+ <li>
+ <strong>SystemInit()</strong> configures the clock system and also configures
+ an existing external memory controller.
+ </li>
+ <li>
+ <strong>SystemInit()</strong> must not use global variables.
+ </li>
+ <li>
+ <strong>SystemCoreClock</strong> is initialized with a correct predefined value.
+ </li>
+ <li>
+ Additional function <strong>void SystemCoreClockUpdate (void)</strong> is provided.<br>
+ <strong>SystemCoreClockUpdate()</strong> updates the variable <strong>SystemCoreClock</strong>
+ and must be called whenever the core clock is changed.<br>
+ <strong>SystemCoreClockUpdate()</strong> evaluates the clock register settings and calculates
+ the current core clock.
+ </li>
+</ul>
+
+
+<h2>4. Advanced Debug Functions</h2>
+<p>
+ ITM communication channel is only capable for OUT direction. To allow also communication for
+ IN direction a simple concept is provided.
+</p>
+<ul>
+ <li>
+ Global variable <strong>volatile int ITM_RxBuffer</strong> used for IN data.
+ </li>
+ <li>
+ Function <strong>int ITM_CheckChar (void)</strong> checks if a new character is available.
+ </li>
+ <li>
+ Function <strong>int ITM_ReceiveChar (void)</strong> retrieves the new character.
+ </li>
+</ul>
+
+<p>
+ For detailed explanation see file <strong>CMSIS debug support.htm</strong>.
+</p>
+
+
+<h2>5. Core Register Bit Definitions</h2>
+<p>
+ Files core_cm3.h and core_cm0.h contain now bit definitions for Core Registers. The name for the
+ defines correspond with the Cortex-M Technical Reference Manual.
+</p>
+<p>
+ e.g. SysTick structure with bit definitions
+</p>
+<pre>
+/** @addtogroup CMSIS_CM3_SysTick CMSIS CM3 SysTick
+ memory mapped structure for SysTick
+ @{

+ __IO uint32_t VAL; /*!< Offset: 0x08 SysTick Current Value Register */
+ __I uint32_t CALIB; /*!< Offset: 0x0C SysTick Calibration Register */
+} SysTick_Type;
+
+/* SysTick Control / Status Register Definitions */
+#define SysTick_CTRL_COUNTFLAG_Pos 16 /*!< SysTick CTRL: COUNTFLAG Position */

+#define SysTick_CALIB_TENMS_Msk (0xFFFFFFul << SysTick_VAL_CURRENT_Pos) /*!< SysTick CALIB: TENMS Mask */
+/*@}*/ /* end of group CMSIS_CM3_SysTick */</pre>
+
+<h2>7. DoxyGen Tags</h2>
+<p>
+ DoxyGen tags in files core_cm3.[c,h] and core_cm0.[c,h] are reworked to create proper documentation
+ using DoxyGen.
+</p>
+
+<h2>8. Folder Structure</h2>
+<p>
+ The folder structure is changed to differentiate the single support packages.
+</p>
+
+ <ul>
+ <li>CM0</li>
+ <li>CM3
+ <ul>
+ <li>CoreSupport</li>
+ <li>DeviceSupport</li>

+ <li>...</li>
+ </ul>
+ </li>
+ </ul>
+ </li>
+
+ <li>Documentation</li>
+ </ul>
+
+<h2>9. Open Points</h2>
+<p>
+ Following points need to be clarified and solved:
+</p>
+<ul>
+ <li>
+ <p>
+ Equivalent C and Assembler startup files.
+ </p>
+ <p>
+ Is there a need for having C startup files although assembler startup files are
+ very efficient and do not need to be changed?
+ <p/>
+ </li>
+ <li>
+ <p>
+ Placing of HEAP in external RAM.
+ </p>
+ <p>
+ It must be possible to place HEAP in external RAM if the device supports an
+ external memory controller.
+ </p>
+ </li>
+ <li>
+ <p>
+ Placing of STACK /HEAP.
+ </p>
+ <p>
+ STACK should always be placed at the end of internal RAM.
+ </p>
+ <p>
+ If HEAP is placed in internal RAM than it should be placed after RW ZI section.
+ </p>
+ </li>
+ <li>
+ <p>
+ Removing core_cm3.c and core_cm0.c.
+ </p>
+ <p>
+ On a long term the functions in core_cm3.c and core_cm0.c must be replaced with
+ appropriate compiler intrinsics.
+ </p>
+ </li>
+</ul>
+
+
+<h2>10. Limitations</h2>
+<p>
+ The following limitations are not covered with the current CMSIS version:
+</p>
+<ul>
+ <li>
+ No <strong>C startup files</strong> for ARM toolchain are provided.
+ </li>
+ <li>
+ No <strong>C startup files</strong> for GNU toolchain are provided.
+ </li>
+ <li>
+ No <strong>C startup files</strong> for IAR toolchain are provided.
+ </li>
+ <li>
+ No <strong>Tasking</strong> projects are provided yet.
+ </li>
+</ul>

+<h1>CMSIS Debug Support</h1>
+
+<hr>
+
+<h2>Cortex-M3 ITM Debug Access</h2>
+<p>
+ The Cortex-M3 incorporates the Instrumented Trace Macrocell (ITM) that provides together with
+ the Serial Viewer Output trace capabilities for the microcontroller system. The ITM has
+ 32 communication channels which are able to transmit 32 / 16 / 8 bit values; two ITM
+ communication channels are used by CMSIS to output the following information:
+</p>
+<ul>
+ <li>ITM Channel 0: used for printf-style output via the debug interface.</li>
+ <li>ITM Channel 31: is reserved for RTOS kernel awareness debugging.</li>
+</ul>
+
+<h2>Debug IN / OUT functions</h2>
+<p>CMSIS provides following debug functions:</p>
+<ul>
+ <li>ITM_SendChar (uses ITM channel 0)</li>
+ <li>ITM_ReceiveChar (uses global variable)</li>
+ <li>ITM_CheckChar (uses global variable)</li>
+</ul>
+
+<h3>ITM_SendChar</h3>
+<p>
+ <strong>ITM_SendChar</strong> is used to transmit a character over ITM channel 0 from
+ the microcontroller system to the debug system. <br>
+ Only a 8 bit value is transmitted.
+</p>
+<pre>
+static __INLINE uint32_t ITM_SendChar (uint32_t ch)
+{
+ /* check if debugger connected and ITM channel enabled for tracing */
+ if ((CoreDebug->DEMCR & CoreDebug_DEMCR_TRCENA) &&
+ (ITM->TCR & ITM_TCR_ITMENA) &&
+ (ITM->TER & (1UL << 0)) )
+ {
+ while (ITM->PORT[0].u32 == 0);
+ ITM->PORT[0].u8 = (uint8_t)ch;
+ }
+ return (ch);
+}</pre>
+
+<h3>ITM_ReceiveChar</h3>
+<p>
+ ITM communication channel is only capable for OUT direction. For IN direction
+ a globel variable is used. A simple mechansim detects if a character is received.
+ The project to test need to be build with debug information.
+</p>
+
+<p>
+ The globale variable <strong>ITM_RxBuffer</strong> is used to transmit a 8 bit value from debug system
+ to microcontroller system. <strong>ITM_RxBuffer</strong> is 32 bit wide to enshure a proper handshake.
+</p>
+<pre>
+extern volatile int ITM_RxBuffer; /* variable to receive characters */
+</pre>
+<p>
+ A dedicated bit pattern is used to determin if <strong>ITM_RxBuffer</strong> is empty
+ or contains a valid value.
+</p>
+<pre>
+#define ITM_RXBUFFER_EMPTY 0x5AA55AA5 /* value identifying ITM_RxBuffer is ready for next character */
+</pre>
+<p>
+ <strong>ITM_ReceiveChar</strong> is used to receive a 8 bit value from the debug system. The function is nonblocking.
+ It returns the received character or '-1' if no character was available.
+</p>
+<pre>
+static __INLINE int ITM_ReceiveChar (void) {
+ int ch = -1; /* no character available */
+
+ if (ITM_RxBuffer != ITM_RXBUFFER_EMPTY) {
+ ch = ITM_RxBuffer;
+ ITM_RxBuffer = ITM_RXBUFFER_EMPTY; /* ready for next character */
+ }
+
+ return (ch);
+}
+</pre>
+
+<h3>ITM_CheckChar</h3>
+<p>
+ <strong>ITM_CheckChar</strong> is used to check if a character is received.
+</p>
+<pre>
+static __INLINE int ITM_CheckChar (void) {
+
+ if (ITM_RxBuffer == ITM_RXBUFFER_EMPTY) {
+ return (0); /* no character available */
+ } else {
+ return (1); /* character available */
+ }
+}</pre>
+
+
+<h2>ITM Debug Support in uVision</h2>
+<p>
+ uVision uses in a debug session the <strong>Debug (printf) Viewer</strong> window to
+ display the debug data.
+</p>
+<p>Direction microcontroller system -> uVision:</p>
+<ul>
+ <li>
+ Characters received via ITM communication channel 0 are written in a printf style
+ to <strong>Debug (printf) Viewer</strong> window.
+ </li>
+</ul>
+
+<p>Direction uVision -> microcontroller system:</p>
+<ul>
+ <li>Check if <strong>ITM_RxBuffer</strong> variable is available (only performed once).</li>
+ <li>Read character from <strong>Debug (printf) Viewer</strong> window.</li>
+ <li>If <strong>ITM_RxBuffer</strong> empty write character to <strong>ITM_RxBuffer</strong>.</li>
+</ul>
+
+<p class="Note">Note</p>
+<ul>
+ <li><p>Current solution does not use a buffer machanism for trasmitting the characters.</p>
+ </li>
+</ul>
+
+<h2>RTX Kernel awareness in uVision</h2>
+<p>
+ uVision / RTX are using a simple and efficient solution for RTX Kernel awareness.
+ No format overhead is necessary.<br>
+ uVsion debugger decodes the RTX events via the 32 / 16 / 8 bit ITM write access
+ to ITM communication channel 31.
+</p>
+
+<p>Following RTX events are traced:</p>
+<ul>
+ <li>Task Create / Delete event
+ <ol>
+ <li>32 bit access. Task start address is transmitted</li>
+ <li>16 bit access. Task ID and Create/Delete flag are transmitted<br>
+ High byte holds Create/Delete flag, Low byte holds TASK ID.
+ </li>
+ </ol>
+ </li>
+ <li>Task switch event
+ <ol>
+ <li>8 bit access. Task ID of current task is transmitted</li>
+ </ol>
+ </li>
+</ul>
+
+<p class="Note">Note</p>
+<ul>
+ <li><p>Other RTOS information could be retrieved via memory read access in a polling mode manner.</p>
+ </li>
+</ul>

+<h2><a name="1"></a>About</h2>
+
+<p>
+ The <strong>Cortex Microcontroller Software Interface Standard (CMSIS)</strong> answers the challenges
+ that are faced when software components are deployed to physical microcontroller devices based on a
+ Cortex-M0 or Cortex-M3 processor. The CMSIS will be also expanded to future Cortex-M
+ processor cores (the term Cortex-M is used to indicate that). The CMSIS is defined in close co-operation
+ with various silicon and software vendors and provides a common approach to interface to peripherals,
+ real-time operating systems, and middleware components.
+</p>
+
+<p>ARM provides as part of the CMSIS the following software layers that are
+available for various compiler implementations:</p>
+<ul>
+ <li><strong>Core Peripheral Access Layer</strong>: contains name definitions,
+ address definitions and helper functions to
+ access core registers and peripherals. It defines also a device
+ independent interface for RTOS Kernels that includes debug channel
+ definitions.</li>
+</ul>
+
+<p>These software layers are expanded by Silicon partners with:</p>
+<ul>
+ <li><strong>Device Peripheral Access Layer</strong>: provides definitions
+ for all device peripherals</li>
+ <li><strong>Access Functions for Peripherals (optional)</strong>: provides
+ additional helper functions for peripherals</li>
+</ul>
+
+<p>CMSIS defines for a Cortex-M Microcontroller System:</p>
+<ul>
+ <li style="text-align: left;">A common way to access peripheral registers
+ and a common way to define exception vectors.</li>
+ <li style="text-align: left;">The register names of the <strong>Core
+ Peripherals</strong> and<strong> </strong>the names of the <strong>Core
+ Exception Vectors</strong>.</li>
+ <li>An device independent interface for RTOS Kernels including a debug
+ channel.</li>
+</ul>
+
+<p>
+ By using CMSIS compliant software components, the user can easier re-use template code.
+ CMSIS is intended to enable the combination of software components from multiple middleware vendors.
+</p>
+
+<h2><a name="2"></a>Coding Rules and Conventions</h2>
+
+<p>
+ The following section describes the coding rules and conventions used in the CMSIS
+ implementation. It contains also information about data types and version number information.
+</p>
+
+<h3>Essentials</h3>
+<ul>
+ <li>The CMSIS C code conforms to MISRA 2004 rules. In case of MISRA violations,
+ there are disable and enable sequences for PC-LINT inserted.</li>
+ <li>ANSI standard data types defined in the ANSI C header file
+ <strong><stdint.h></strong> are used.</li>
+ <li>#define constants that include expressions must be enclosed by
+ parenthesis.</li>
+ <li>Variables and parameters have a complete data type.</li>
+ <li>All functions in the <strong>Core Peripheral Access Layer</strong> are
+ re-entrant.</li>
+ <li>The <strong>Core Peripheral Access Layer</strong> has no blocking code
+ (which means that wait/query loops are done at other software layers).</li>
+ <li>For each exception/interrupt there is definition for:
+ <ul>
+ <li>an exception/interrupt handler with the postfix <strong>_Handler </strong>
+ (for exceptions) or <strong>_IRQHandler</strong> (for interrupts).</li>
+ <li>a default exception/interrupt handler (weak definition) that contains an endless loop.</li>
+ <li>a #define of the interrupt number with the postfix <strong>_IRQn</strong>.</li>
+ </ul></li>
+</ul>
+
+<h3>Recommendations</h3>
+
+<p>The CMSIS recommends the following conventions for identifiers.</p>
+<ul>
+ <li><strong>CAPITAL</strong> names to identify Core Registers, Peripheral Registers, and CPU Instructions.</li>
+ <li><strong>CamelCase</strong> names to identify peripherals access functions and interrupts.</li>
+ <li><strong>PERIPHERAL_</strong> prefix to identify functions that belong to specify peripherals.</li>
+ <li><strong>Doxygen</strong> comments for all functions are included as described under <strong>Function Comments</strong> below.</li>
+</ul>
+
+<b>Comments</b>
+
+<ul>
+ <li>Comments use the ANSI C90 style (<em>/* comment */</em>) or C++ style
+ (<em>// comment</em>). It is assumed that the programming tools support today
+ consistently the C++ comment style.</li>
+ <li><strong>Function Comments</strong> provide for each function the following information:
+ <ul>
+ <li>one-line brief function overview.</li>
+ <li>detailed parameter explanation.</li>
+ <li>detailed information about return values.</li>
+ <li>detailed description of the actual function.</li>
+ </ul>
+ <p><b>Doxygen Example:</b></p>
+ <pre>
+/**
+ * @brief Enable Interrupt in NVIC Interrupt Controller
+ * @param IRQn interrupt number that specifies the interrupt
+ * @return none.
+ * Enable the specified interrupt in the NVIC Interrupt Controller.
+ * Other settings of the interrupt such as priority are not affected.
+ */</pre>
+ </li>
+</ul>
+
+<h3>Data Types and IO Type Qualifiers</h3>
+
+<p>
+ The <strong>Cortex-M HAL</strong> uses the standard types from the standard ANSI C header file
+ <strong><stdint.h></strong>. <strong>IO Type Qualifiers</strong> are used to specify the access
+ to peripheral variables. IO Type Qualifiers are indented to be used for automatic generation of
+ debug information of peripheral registers.

+<h4>Device Peripheral Access Layer</h4>
+<p>
+ Each peripheral uses a prefix which consists of <strong><device abbreviation>_</strong>
+ and <strong><peripheral name>_</strong> to identify peripheral registers that access this
+ specific peripheral. The intention of this is to avoid name collisions caused
+ due to short names. If more than one peripheral of the same type exists,
+ identifiers have a postfix (digit or letter). For example:
+</p>
+<ul>
+ <li><device abbreviation>_UART_Type: defines the generic register layout for all UART channels in a device.
+ <pre>
+typedef struct
+{
+ union {
+ __I uint8_t RBR; /*!< Offset: 0x000 Receiver Buffer Register */
+ __O uint8_t THR; /*!< Offset: 0x000 Transmit Holding Register */
+ __IO uint8_t DLL; /*!< Offset: 0x000 Divisor Latch LSB */
+ uint32_t RESERVED0;
+ };
+ union {
+ __IO uint8_t DLM; /*!< Offset: 0x004 Divisor Latch MSB */
+ __IO uint32_t IER; /*!< Offset: 0x004 Interrupt Enable Register */
+ };
+ union {
+ __I uint32_t IIR; /*!< Offset: 0x008 Interrupt ID Register */
+ __O uint8_t FCR; /*!< Offset: 0x008 FIFO Control Register */
+ };
+ __IO uint8_t LCR; /*!< Offset: 0x00C Line Control Register */
+ uint8_t RESERVED1[7];
+ __I uint8_t LSR; /*!< Offset: 0x014 Line Status Register */
+ uint8_t RESERVED2[7];
+ __IO uint8_t SCR; /*!< Offset: 0x01C Scratch Pad Register */
+ uint8_t RESERVED3[3];
+ __IO uint32_t ACR; /*!< Offset: 0x020 Autobaud Control Register */
+ __IO uint8_t ICR; /*!< Offset: 0x024 IrDA Control Register */
+ uint8_t RESERVED4[3];
+ __IO uint8_t FDR; /*!< Offset: 0x028 Fractional Divider Register */
+ uint8_t RESERVED5[7];
+ __IO uint8_t TER; /*!< Offset: 0x030 Transmit Enable Register */
+ uint8_t RESERVED6[39];
+ __I uint8_t FIFOLVL; /*!< Offset: 0x058 FIFO Level Register */
+} LPC_UART_TypeDef;</pre>
+ </li>
+ <li><device abbreviation>_UART1: is a pointer to a register structure that refers to a specific UART.
+ For example UART1->DR is the data register of UART1.
+ <pre>
+#define LPC_UART2 ((LPC_UART_TypeDef *) LPC_UART2_BASE )
+#define LPC_UART3 ((LPC_UART_TypeDef *) LPC_UART3_BASE )</pre>
+ </li>
+</ul>
+
+<h5>Minimal Requiements</h5>
+<p>
+ To access the peripheral registers and related function in a device the files <strong><em>device.h</em></strong>
+ and <strong>core_cm0.h</strong> / <strong>core_cm3.h</strong> defines as a minimum:
+</p>
+<ul>
+ <li>The <strong>Register Layout Typedef</strong> for each peripheral that defines all register names.
+ Names that start with RESERVE are used to introduce space into the structure to adjust the addresses of
+ the peripheral registers. For example:
+ <pre>
+typedef struct {
+ __IO uint32_t CTRL; /* SysTick Control and Status Register */
+ __IO uint32_t LOAD; /* SysTick Reload Value Register */
+ __IO uint32_t VAL; /* SysTick Current Value Register */
+ __I uint32_t CALIB; /* SysTick Calibration Register */
+ } SysTick_Type;</pre>
+ </li>
+
+ <li>
+ <strong>Base Address</strong> for each peripheral (in case of multiple peripherals
+ that use the same <strong>register layout typedef</strong> multiple base addresses are defined). For example:
+ <pre>
+#define SysTick_BASE (SCS_BASE + 0x0010) /* SysTick Base Address */</pre>
+ </li>
+
+ <li>
+ <strong>Access Definition</strong> for each peripheral (in case of multiple peripherals that use
+ the same <strong>register layout typedef</strong> multiple access definitions exist, i.e. LPC_UART0,
+ LPC_UART2). For Example:
+ <pre>
+#define SysTick ((SysTick_Type *) SysTick_BASE) /* SysTick access definition */</pre>
+ </li>
+</ul>
+
+<p>
+ These definitions allow to access the peripheral registers from user code with simple assignments like:
+</p>
+<pre>SysTick->CTRL = 0;</pre>
+
+<h5>Optional Features</h5>
+<p>In addition the <em> <strong>device.h </strong></em>file may define:</p>
+<ul>
+ <li>
+ #define constants that simplify access to the peripheral registers.
+ These constant define bit-positions or other specific patterns are that required for the
+ programming of the peripheral registers. The identifiers used start with
+ <strong><device abbreviation>_</strong> and <strong><peripheral name>_</strong>.
+ It is recommended to use CAPITAL letters for such #define constants.
+ </li>
+ <li>
+ Functions that perform more complex functions with the peripheral (i.e. status query before
+ a sending register is accessed). Again these function start with
+ <strong><device abbreviation>_</strong> and <strong><peripheral name>_</strong>.
+ </li>
+</ul>
+
+<h3>core_cm0.h and core_cm0.c</h3>
+<p>
+ File <b>core_cm0.h</b> describes the data structures for the Cortex-M0 core peripherals and does
+ the address mapping of this structures. It also provides basic access to the Cortex-M0 core registers
+ and core peripherals with efficient functions (defined as <strong>static inline</strong>).
+</p>
+<p>
+ File <b>core_cm0.c</b> defines several helper functions that access processor registers.
+</p>
+<p>Together these files implement the <a href="#4">Core Peripheral Access Layer</a> for a Cortex-M0.</p>
+
+<h3>core_cm3.h and core_cm3.c</h3>
+<p>
+ File <b>core_cm3.h</b> describes the data structures for the Cortex-M3 core peripherals and does
+ the address mapping of this structures. It also provides basic access to the Cortex-M3 core registers

+<p>Together these files implement the <a href="#4">Core Peripheral Access Layer</a> for a Cortex-M3.</p>
+
+<h3>startup_<em>device</em></h3>
+<p>
+ A template file for <strong>startup_<em>device</em></strong> is provided by ARM for each supported
+ compiler. It is adapted by the silicon vendor to include interrupt vectors for all device specific
+ interrupt handlers. Each interrupt handler is defined as <strong><em>weak</em></strong> function
+ to an dummy handler. Therefore the interrupt handler can be directly used in application software
+ without any requirements to adapt the <strong>startup_<em>device</em></strong> file.
+</p>
+<p>
+ The following exception names are fixed and define the start of the vector table for a Cortex-M0:

+ The CMSIS provides access to the NVIC via the register interface structure and several helper
+ functions that simplify the setup of the NVIC. The CMSIS HAL uses IRQ numbers (IRQn) to
+ identify the interrupts. The first device interrupt has the IRQn value 0. Therefore negative
+ IRQn values are used for processor core exceptions.
+</p>

+ <li>ITM Channel 0: implements the <strong>ITM_SendChar</strong> function
+ which can be used for printf-style output via the debug interface.</li>

+ may use the Privileged level for program execution. ITM
+ channels have 4 groups with 8 channels each, whereby each group can be
+ configured for access rights in the Unprivileged level. The ITM channel 0
+ may be therefore enabled for the user task whereas ITM channel 31 may be
