This register is non-volatile and will be maintained through power and reset cycles. A valid OEM password is required for access
to this register.
Default value
Serial address
Byte address
This register reflects (reads back) the value being sent to the BIAS DAC (APCSET0, APCSET1, or APCSET2 whichever is
selected, with temperature compensation applied).
A valid OEM password is required for access to this register.

Operation
0: GPO (general purpose output)
1: Reset output
0 = The TXFIN input is active-low
1 = The TXFIN input is active-high
This bit is ignored if TXFINM = 0
0 = GPO output is open-drain
1 = GPO output is push-pull
This bit is ignored if GPOM = 0
0 = RRSOUT output
1 = GPO output
0 = Set the GPO pin low
1 = Set the GPO pin high
This bit is ignored if GPOM = 0
0 = SHDN output
1 = TXFIN input
0 = RXLOS fault enabled, and the RXLOS output is enabled
for normal operation
1 = RXLOS fault disabled; also, the RXLOS output is
disabled, and will remain low
0 = External calibration mode
1 = Internal calibration.(the MIC3003’s ALU applies slope
and offset coefficients to the ALU results as necessary)
