;* 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.

; 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:

; table register (VTOR) is initialized to this address if != 0.
