Operation
Read fuse low/high byte. Bit “0” =
programmed, “1” = unprogrammed.
See
details.
Set fuse low/high byte. Set bit to “0” to
program, “1” to unprogram. See
Bytes” on page 103
Read Signature Byte o at address b.
Read Calibration Byte. See
“Calibration Bytes” on page 104
If o = “1”, a programming operation is
still busy. Wait until this bit returns to
“0” before applying another command.
