Operation
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
page 296
Write Lock bits. Set bits = “0” to
program Lock bits. See
page 296
Read Signature Byte o at address b.
Set bits = “0” to program, “1” to
unprogram. See Table XXX on page
XXX for details.
Set bits = “0” to program, “1” to
unprogram. See
299
Set bits = “0” to program, “1” to
unprogram. See
298
Read Fuse bits. “0” = programmed, “1”
= unprogrammed. See Table XXX on
page XXX for details.
Read Fuse High bits. “0” =
pro-grammed, “1” = unprogrammed.
See
details.
Read Extended Fuse bits. “0” =
pro-grammed, “1” = unprogrammed.
See
details.
Read Calibration Byte
If o = “1”, a programming operation is
still busy. Wait until this bit returns to
“0” before applying another command.
