;* @brief   PY32F403xx 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 CortexM4 processor is in Thread mode,
;*          priority is Privileged, and the Stack is set to Main.
