On-Chip FLASH Programming Routines, Rev. 4

Freescale Semiconductor
How to Use the Routines
Example 7: Erasing an Entire Array
Example 7 shows how to erase an entire array:
ERARNGE equ $0387 ;LB8 ERARNGE jump address
mov #$08,CPUSPD ;fop = 2.0MHz in this example
mov #$40,CTRLBYT ;Select Mass erase operation
ldhx #$E000 ;Load any FLASH address to H:X
jsr ERARNGE ;Call ERARNGE routine
Example 8: Erasing a Page
Example 8 shows how to erase a page from $E100 through $E13F:
ERARNGE equ $0387 ;LB8 ERARNGE jump address
mov #$14,CPUSPD ;fop = 4.9152MHz in this example
mov #$00,CTRLBYT ;Select Page erase operation
ldhx #$E121 ;Load any address within the
; page to H:X
jsr ERARNGE ;Call ERARNGE routine
If the FLASH locations that you want to erase are protected due to the value in the FLASH block protect
register (FLBPR), the erase operation will not be successful. However when a high voltage (V
tst
) is
applied to the IRQ pin, the block protection is bypassed.
When the FLASH security check fails in the normal monitor mode, the FLASH can be re-accessed by
erasing the entire FLASH array. To override the FLASH security mechanism and erase the FLASH array
using this routine, registers H and X must contain the address of the FLASH block protect register
(FLBPR).
