If a Flash location has been erased, it can be pro-
grammed using table write instructions to write an
instruction word (24-bit) into the write latch. The
TBLPAG register is loaded with the 8 Most Significant
Bytes of the Flash address. The TBLWTL and TBLWTH

PROGRAMMING A SINGLE WORD OF FLASH PROGRAM MEMORY
Preliminary
;
;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
instructions write the desired data into the write latches
and specify the lower 16 bits of the program memory
address to write to. To configure the NVMCON register
for a word write, set the NVMOP bits (NVMCON<3:0>)
to ‘0011’. The write is performed by executing the
unlock sequence and setting the WR bit (see
Example 4-4).
