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 a:b.
Write data i to EEPROM
memory at address a:b.
Load data i to EEPROM
memory page buffer. After
data is loaded, program
EEPROM page.
Write EEPROM page at
address a:b.
Read Lock bits. “0” =
programmed, “1” =
unprogrammed. See
25-1 on page 278
Write Lock bits. Set bits = “0”
to program Lock bits. See
Table 25-1 on page 278
details.
