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.
Read Lock bits. “0” = programmed,
“1” = unprogrammed. See
96 on page 237
Write Lock bits. Set bits = “0” to
program Lock bits. See
on page 237
Read Signature Byte o at address
b.
Set bits = “0” to program, “1” to
unprogram. See
page 239
Set bits = “0” to program, “1” to
unprogram. See
page 238
Read Fuse bits. “0” = programmed,
“1” = unprogrammed. See
