;* @brief   PY32F420xx devices vector table for EWARM toolchain.
;*          This module performs:
;*          - Set the initial SP
;*          - Set the initial PC == __iar_program_start
;*          - 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.

; The modules in this file are included in the libraries, and may be replaced
; by any user-defined modules that define the PUBLIC symbol _program_start or
; a user defined start symbol.
; To override the cstartup defined in the library, simply add your modified
; version to the workbench project.
;
; The vector table is normally located at address 0.
; When debugging in RAM, it can be located in RAM, aligned to at least 2^6.
; The name "__vector_table" has special meaning for C-SPY:
; it is where the SP start value is found, and the NVIC vector
; table register (VTOR) is initialized to this address if != 0.
