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)
