6.6.3
LOADING WRITE LATCHES
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:
LOADING WRITE LATCHES
6.6.4
INITIATING THE PROGRAMMING
SEQUENCE
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
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.
EXAMPLE 6-3:
INITIATING A PROGRAMMING SEQUENCE
; Set up a pointer to the first program memory location to be written
; program memory selected, and writes enabled
MOV
#0x0000,W0
