* @date 13-November-2015
|
||||
* @brief STM32F401xCxx Devices vector table for GCC based toolchains.
|
||||
* 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-M4 processor is in Thread mode,
|
||||
* priority is Privileged, and the Stack is set to Main.
