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 t
PGMR
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 V
PP
pin while programming, but it should be equal to V
operations.
