Operation
Set bits = “0” to program, “1” to
unprogram. See
290
Set bits = “0” to program, “1” to
unprogram. See
288
Read Fuse bits. “0” = programmed, “1”
= unprogrammed. See
page 293
Read Fuse High bits. “0” = pro-
grammed, “1” = unprogrammed. See
Table 27-6 on page 290
Read Extended Fuse bits. “0” = pro-
grammed, “1” = unprogrammed. See
Table 27-4 on page 288
Read Calibration Byte
If o = “1”, a programming operation is
still busy. Wait until this bit returns to
“0” before applying another command
