Operation
Enable SPI Serial Programming
after RESET goes low.
Chip Erase EEPROM and Flash.
Read H (high or low) data o from
Program memory at word address
a:b.
Write H (high or low) data i to
Program Memory page at word
address b. Data low byte must be
loaded before data high byte is
applied within the same address.
Write Program Memory Page at
address a:b.
Read data o from EEPROM
memory at address a:b.
Write data i to EEPROM memory
at address a:b.
Read Lock bits. “0” = programmed,
“1” = unprogrammed. See
