Operation
Enable 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 b.
Write data i to EEPROM memory at
address b.
Load data i to EEPROM memory page
buffer. After data is loaded, program
EEPROM page.
Write EEPROM page at address b.
