INITIATING A PROGRAMMING SEQUENCE – ‘C’ LANGUAGE CODE
PROGRAMMING A SINGLE WORD OF FLASH PROGRAM MEMORY
// Block all interrupts for next 5 instructions
// Perform unlock sequence and set WR
Preliminary
; Block all interrupts
; Write the 55 key
;
; Write the AA key
; Start the erase sequence
; 2 NOPs required after setting WR
;
; Wait for the sequence to be completed
;
;
;Initialize PM Page Boundary SFR
;Initialize a register with program memory address
;
;
; Write PM low word into program latch
; Write PM high byte into program latch
;
; Set NVMOP bits to 0011
; Disable interrupts while the KEY sequence is written
; Write the key sequence
; Start the write cycle
