Operation
Write EEPROM page at address a:b.
Read Lock bits. “0” = programmed, “1” =
unprogrammed. See
247
Write Lock bits. Set bits = “0” to program
Lock bits. See
details.
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
for details.
Set bits = “0” to program, “1” to
unprogram. See
for details.
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
page 251
Read Extended Fuse bits. “0” = pro-
grammed, “1” = unprogrammed. See
Table 21-4 on page 249
Read Calibration Byte
If o = “1”, a programming operation is still
busy. Wait until this bit returns to “0”
before applying another command.
