11.9
The procedure for writing data EEPROM is very similar
to the procedure for writing code memory, except that
fewer words are programmed in each operation. When
writing data EEPROM, one row of data EEPROM is
programmed at a time. Each row consists of sixteen
16-bit data words. Since fewer words are programmed

value is required to write to data EEPROM, and that the
TBLPAG register is hard-coded to 0x7F (the upper byte
address of all locations of data EEPROM).
