NOTE:
NOTE:
Use the following procedure to program a byte of EPROM:
Writing logic 1s to both the ELAT and EPGM bits with a single instruction
sets only the ELAT bit. EPGM must be set by a separate instruction in
the programming sequence.
Writing to an invalid address prevents the programming voltage from
being applied.
1. Apply V
2. Set the ELAT bit.
3. Write to any user EPROM address.
4. Set the EPGM bit.
5. Wait for a time, t
6. Clear the ELAT and EPGM bits.
