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.
Read Lock bits. “0” = programmed, “1”
= unprogrammed. See Table 42 on
page 103 for details.
Write Lock bits. Set bits = “0” to
program Lock bits. See Table 42 on
page 103 for details.
Read Signature Byte o at address b.
Set bits = “0” to program, “1” to
unprogram.
Set bits = “0” to program, “1” to
unprogram. See Table 36 on page 85
for details.
Read Fuse bits. “0” = programmed, “1”
= unprogrammed.
Read Fuse High bits. “0” = pro-
grammed, “1” = unprogrammed. See
Table 36 on page 85 for details.
Read Calibration Byte
If o = “1”, a programming operation is
still busy. Wait until this bit returns to
“0” before applying another command.
