|
||
|
* @brief STM32L432xx 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,
|
||
|
* - Configure the clock system
|
||
|
* - Branches to main in the C library (which eventually
|
||
|
* calls main()).
|
||
|
* After Reset the Cortex-M4 processor is in Thread mode,
|
||
|
* priority is Privileged, and the Stack is set to Main.
