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 Table 121 on page 323 for details.
Write Lock bits. Set bits = “0” to program Lock
bits. See Table 121 on page 323 for details.
Read Signature Byte o at address b.
Set bits = “0” to program, “1” to unprogram. See
Table 125 on page 325 for details.
Set bits = “0” to program, “1” to unprogram. See
Table 124 on page 324 for details.
Set bits = “0” to program, “1” to unprogram. See
Table 123 on page 324 for details.
Read Fuse bits. “0” = programmed, “1” =
unprogrammed. See Table 125 on page 325 for
details.
Read Fuse High bits. “0” = pro-grammed, “1” =
unprogrammed. See Table 124 on page 324 for
details.
