Operation
Read Lock bits. “0” = programmed, “1”
= unprogrammed. See
page 158
Write Lock bits. Set bits = “0” to
program Lock bits. See
page 158
Read Signature Byte o at address b.
Set bits = “0” to program, “1” to
unprogram.
Set bits = “0” to program, “1” to
unprogram.
Set bits = “0” to program, “1” to
unprogram.
Read Fuse bits. “0” = programmed, “1”
= unprogrammed.
Read Fuse High bits. “0” = pro-
grammed, “1” = unprogrammed.
Read Extended Fuse bits. “0” = pro-
grammed, “1” = unprogrammed.
Read Calibration Byte at address b.
If o = “1”, a programming operation is
still busy. Wait until this bit returns to
“0” before applying another command.
