Each LSB of RXOPl represents 25.6µW and each LSB of RXOPl represents 0.1µW. RXOPh is to be used in conjunction with
RXOPl to yield a sixteen-bit value. The values in RXOPh:RXOPl are in an unsigned binary format. The value in this register is
uncalibrated. The host should process the results using the scale factor and offset provided. See the External Calibration
section.

Notes:
6. RXOPh will contain measured data after one A/D conversion cycle.
Operation
1 = disabled, 0 = enabled, read only.
1 = disabled; 0 = enabled.
Reserved - always write as zero.
1 = high; 0 = low.
1 = high (2Gbps); 0 = low (1Gbps).
1 = high (fault); 0 = low (no fault).
1 = high (loss of signal); 0 = low (no loss
of signal).
0 = POR complete, analog data ready;
1 = POR in progress.
