Program instruction:

– write 40h or 10h command

– write Address & Data

(memory enters read status state after

the Program instruction)

do:

– read status register (E or G must be

toggled) if PES instruction given execute

suspend program loop

while b7 = 1

If b3 = 1, VPP invalid error:

– error handler

If b4 = 1, Program error:

– error handler

If b1 = 1, Program to protected block error:

– error handler

Note: 1. Status check of b1 (Protected Block), b3 (VPP Invalid) and b4 (Program Error) can be made after each program operation or after

a program sequence.

2. If an error is found, the Status Register must be cleared (CLRS instruction) before further P/E.C. operations.
