6.5.2
The PIC18F46J11 family of devices has a feature that
allows programming a single word (two bytes). This
feature is enabled when the WPROG bit is set. If the
memory location is already erased, the following
sequence is required to enable this feature:
1.
2.

PROGRAM_MEMORY
Load the Table Pointer register with the address
of the data to be written. (It must be an even
address.)
Write the 2 bytes into the holding registers by
performing table writes. (Do not post-increment
on the second table write.)

Set the WREN bit (EECON1<2>) to enable
writes and the WPROG bit (EECON1<5>) to
select Word Write mode.
Disable interrupts.
Write 55h to EECON2.
Write 0AAh to EECON2.
Set the WR bit; this will begin the write cycle.
The CPU will stall for the duration of the write for
T
Re-enable interrupts.
