-* Function name: PowerON_Reset_PC\r
-* Description : This function is the MCU's entry point from a power-on reset.\r
-* The following steps are taken in the startup code:\r
-* 1. The User Stack Pointer (USP) and Interrupt Stack Pointer (ISP) are both set immediately after entry \r
-* to this function. The USP and ISP stack sizes are set in the file stacksct.h.\r
-* Default sizes are USP=4K and ISP=1K.\r
-* 2. The interrupt vector base register is set to point to the beginning of the relocatable interrupt \r
-* vector table.\r
-* 3. The MCU is setup for floating point operations by setting the initial value of the Floating Point \r
-* Status Word (FPSW).\r
-* 4. The MCU operating frequency is set by configuring the Clock Generation Circuit (CGC) in\r
-* operating_frequency_set.\r
-* 5. Calls are made to functions to setup the C runtime environment which involves initializing all \r
-* initialed data, zeroing all uninitialized variables, and configuring STDIO if used\r
-* (calls to _INITSCT and _INIT_IOLIB).\r
-* 6. Board-specific hardware setup, including configuring I/O pins on the MCU, in hardware_setup.\r
-* 7. Global interrupts are enabled by setting the I bit in the Program Status Word (PSW), and the stack \r
-* is switched from the ISP to the USP. The initial Interrupt Priority Level is set to zero, enabling \r
-* any interrupts with a priority greater than zero to be serviced.\r
-* 8. The processor is optionally switched to user mode. To run in user mode, set the macro \r
-* RUN_IN_USER_MODE above to a 1.\r
-* 9. The bus error interrupt is enabled to catch any accesses to invalid or reserved areas of memory.\r
-*\r
-* Once this initialization is complete, the user's main() function is called. It should not return.\r
-* Arguments : none\r
-* Return value : none\r
