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.
Read Lock bits. “0” = programmed, “1”
= unprogrammed. See
page 107
Write Lock bits. Set bits = “0” to
program Lock bits. See
page 107
Read Signature Byte o at address b.
Set bits = “0” to program, “1” to
unprogram. See

Set bits = “0” to program, “1” to
unprogram. See

Read Fuse bits. “0” = programmed, “1”
= unprogrammed. See
page 108
Read Fuse high bits.
“0” = programmed,
“1” = unprogrammed. See
