PH8.DS03/Modes+mem
During EEPROM programming, the ROW and BYTE bits of PPROG are not used. If the frequency
of the E clock is 1MHz or less, set the CSEL bit in the OPTION register. Remember that the
EEPROM must be erased by a separate erase operation before programming. The following
example of how to program an EEPROM byte assumes that the appropriate bits in BPROT have
been cleared.
PROG
3.4.2.2
To erase the EEPROM, ensure that the proper bits of the BPROT register are cleared, then
complete the following steps using the PPROG register:
The following is an example of how to bulk erase the 768-byte EEPROM. The CONFIG register is
not affected in this example.

1) Write to PPROG with the ERASE, EELAT and appropriate BYTE and ROW
2) Write to the appropriate EEPROM address with any data. Row erase only
3) Write to PPROG with ERASE, EELAT, EEPGM and the appropriate BYTE
4) Delay for time t
5) Clear the EEPGM bit in PPROG to turn off the high voltage.
6) Clear the PPROG register to reconfigure the EEPROM address and data
