Operation
Read Fuse high bits. “0” = pro-
grammed, “1” = unprogrammed.
See
details.
Read Extended Fuse bits. “0” =
pro-grammed, “1” =
unprogrammed. See
page 232
Read Calibration Byte
If o = “1”, a programming operation
is still busy. Wait until this bit
returns to “0” before applying
another command.
