; This program demonstrates how to erase a flash memory chip that is not
; supported by the ROM loader of the networked microcontrollers.
;
; To build this program, run
; macro chiperase.asm
; a390 -d -l chiperase.mpp
;
; To execute, load into SRAM and use loader commands 'B0', 'X0'.
;
; Note: When using MTK to load this code, be sure to disable the "Clear Heap"
; option.
;
; The flash memory we want to erase is connected to CE2\, or address 400000h,
; since the ROM uses 2 MB per chip enable.
