|
|
;* Description : ACM32F4 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-M33 processor is in Thread mode,
|
||
|
|
;* priority is Privileged, and the Stack is set to Main.
