B.5.2 Programming Sequence
The EPROM programming sequence is:
1.
Set the ELAT bit
2.
Write the data to the address to be programmed
3.
Set the PGM bit
4.
Delay for a time tPGMR
5.
Clear the PGM bit
6.
Clear the ELAT bit
The last two steps must be performed with separate CPU writes.
CAUTION
It is important to remember that an external programming voltage must be applied
to the VPP pin while programming, but it should be equal to VDD during normal
operations.
Figure B-2 shows the ow required to successfully program the EPROM.
