6 ;* Description : STM32F401xc devices vector table for MDK-ARM toolchain.
|
|
|
7 ;* This module performs:
|
|
|
8 ;* - Set the initial SP
|
|
|
9 ;* - Set the initial PC == Reset_Handler
|
|
|
10 ;* - Set the vector table entries with the exceptions ISR address
|
|
|
11 ;* - Branches to __main in the C library (which eventually
|
|
|
12 ;* calls main()).
|
|
|
13 ;* After Reset the CortexM4 processor is in Thread mode,
|
|
|
14 ;* priority is Privileged, and the Stack is set to Main.
