Default Value
0000 0000b = 00h (0mW)(6)
Serial Address
A2h = 1010001b
Byte Address
104 = 68h
Each LSB represents 25.6
W. This register 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.

Default Value
0000 0000b = 00h (0mW)(6)
Serial Address
A2h = 1010001b
Byte Address
105 = 69h
Each LSB represents 0.1
W. This register is to be used in conjunction with RXOPh 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 coefficients provided. See the External Calibration section. In the MIC3000, this register
will always return zero. This register is provided for compliance with SFF-8472. It is not used by the MIC3000 when
doing threshold comparisons and setting alarm or warning bits.

D[7]
TXDIS
Reflects the state of the TXDISABLE pin
1 = disabled, 0 = enabled, read only.
D[6]
STXDIS
Soft transmit disable
1 = disabled; 0 = enabled.
D[5]
D[5]
Reserved
Reserved - always write as zero.
D[4]
RSEL
Reflects the state of the RSEL pin
1 = high; 0 = low.
D[3]
SRSEL
Soft rate select
1 = high (2Gbps); 0 = low (1Gbps).
D[2]
TXFLT
Reflects the state of the TXFAULT pin
1 = high (fault); 0 = low (no fault).
D[1]
LOS
Loss of signal. Reflects the state of the LOS pin
1 = high (loss of signal); 0 = low (no loss of signal).
D[0]
POR
MIC3000 power-on status
0 = POR complete, analog data ready;
1 = POR in progress.
Notes:
6. RXOPh will contain measured data after one A/D conversion cycle.
