|
|
;* @brief : PY32F030xx devices vector table for MDK-ARM 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 CortexM0+ processor is in Thread mode,
|
|
;* priority is Privileged, and the Stack is set to Main.
