;* Description : Dragon 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.
|
||
|
|
;* After Reset the Cortex-M0 processor is in Thread mode,
|
||
|
|
;* priority is Privileged, and the Stack is set to Main.
