+<td>V1.2.0 </td><td><p class="starttd">Removed CMSIS Middelware packages</p>
+<p>CMSIS Middleware is on hold from ARM side until a agreement between all CMSIS partners is found. SystemFrequency renamed to SystemCoreClock</p>
+<p>The variable name SystemCoreClock is more precise than SystemFrequency because the variable holds the clock value at which the core is running. Changed startup concept</p>
+<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>
+<p>Changed startup concept</p>
+<ul>
+<li>SystemInit() is called from startup file before premain.</li>
+<li>SystemInit() configures the clock system and also configures an existing external memory controller.</li>
+<li>SystemInit() must not use global variables.</li>
+<li>SystemCoreClock is initialized with a correct predefined value.</li>
+<li>Additional function void SystemCoreClockUpdate (void) is provided.</li>
+<li>SystemCoreClockUpdate() updates the variable SystemCoreClock and must be called whenever the core clock is changed.</li>
+<li>SystemCoreClockUpdate() evaluates the clock register settings and calculates the current core clock.</li>
+</ul>
+<p>Advanced Debug Functions</p>
+<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 volatile int ITM_RxBuffer used for IN data.</li>
+<li>Function int ITM_CheckChar (void) checks if a new character is available.</li>
+<li>Function int ITM_ReceiveChar (void) retrieves the new character.</li>
+</ul>
+<p>For detailed explanation see file CMSIS debug support.htm.</p>
+<p>Core Register Bit Definitions</p>
+<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>
