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