EXAMPLE 6-1:
 2004 Microchip Technology Inc.
; Setup NVMCON for erase operation, multi word write
; program memory selected, and writes enabled
; Init pointer to row to be ERASED
Write 32 instruction words of data from data
RAM into the program Flash write latches.
Program 32 instruction words into program
Flash.
a)
b)
c)
d)
Setup NVMCON register for multi-word,
program Flash, program, and set WREN
bit.
Write ‘55’ to NVMKEY.
Write ‘AA’ to NVMKEY.
Set the WR bit. This will begin program
cycle.

;
; Init NVMCON SFR
;
; Initialize PM Page Boundary SFR
; Intialize in-page EA[15:0] pointer
; Intialize NVMADR SFR
; Block all interrupts with priority <7
; for next 5 instructions
; Write the 0x55 key
;
; Write the 0xAA key
; Start the erase sequence
; Insert two NOPs after the erase
; command is asserted

6.6.2
Example 6-1 shows a code sequence that can be used
to erase a row (32 instructions) of program memory.
e)
f)
Repeat steps 1 through 5 as needed to program
desired amount of program Flash memory.
CPU will stall for duration of the program
cycle.
The WR bit is cleared by the hardware
when program cycle ends.
