1.
Set BS to “1”. This selects high data.
2.
Give WR a negative pulse. This starts programming of the data byte. RDY/BSY
goes low.
3.
Wait until RDY/BSY goes high to program the next byte.
(See Figure 62 for signal waveforms.)
The loaded command and address are retained in the device during programming. For
efficient programming, the following should be considered:
The command needs only be loaded once when writing or reading multiple memory
locations.
Address high byte needs only be loaded before programming a new 256-word page
in the Flash.
Skip writing the data value $FF, that is, the contents of the entire Flash and
EEPROM after a Chip Erase.
These considerations also apply to EEPROM programming and Flash, EEPROM and
signature byte reading.
