6.6.3
Example 6-2 shows a sequence of instructions that can
be used to load the 96 bytes of write latches. 32
TBLWTL and 32 TBLWTH instructions are needed to
load the write latches selected by the table pointer.
EXAMPLE 6-2:
6.6.4
For protection, the write initiate sequence for NVMKEY
must be used to allow any erase or program operation
to proceed. After the programming command has been

Preliminary
; Block all interrupts with priority <7 for

;
; Write the 0x55 key
;
; Write the 0xAA key
; Start the erase sequence
; Insert two NOPs after the erase
; command is asserted
;
; Initialize PM Page Boundary SFR

; Write PM low word into program latch
; Write PM high byte into program latch

executed, the user must wait for the programming time
until programming is complete. The two instructions
following the start of the programming sequence
should be NOPs.
