Operation
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
on page 242
Set bits = “0” to program, “1”
to unprogram. See
25-4 on page 280
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
21-1 on page 242
Read Extended Fuse bits. “0”
= pro-grammed, “1” =
unprogrammed. See
25-4 on page 280
Read Calibration Byte
If o = “1”, a programming
operation is still busy. Wait
until this bit returns to “0”
before applying another
command.
