Operation
Set bits = “0” to program, “1” to
unprogram. See
281
Set bits = “0” to program, “1” to
unprogram. See
280
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
Table 25-5 on page 281
Read Extended Fuse bits. “0” = pro-
grammed, “1” = unprogrammed. See
Table 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.
