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
85 on page 219
Write Lock Bits. Set bits = “0” to
program Lock Bits. See
on page 219
Read Signature Byte o at address
b.
Set bits = “0” to program, “1” to
unprogram. See
page 221
Set bits = “0” to program, “1” to
unprogram. See
page 220
Read Fuse Bits. “0” = programmed,
“1” = unprogrammed. See
88 on page 221
Read Fuse high bits. “0” = pro-
grammed, “1” = unprogrammed.
