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.
