|
* @brief HK32F030MF4P6 devices vector table for GCC toolchain.
|
|
* This module performs:
|
|
* - Set the initial SP
|
|
* - Set the initial PC == Reset_Handler,
|
|
* - Set the vector table entries with the exceptions ISR address
|
|
* - Branches to main in the C library (which eventually calls main()).
|
|
* After Reset the Cortex-M0 processor is in Thread mode,
|
|
* priority is Privileged, and the Stack is set to Main.
