D[5]
D[4]
D[3]
D[2]
D[1]
D[0]
read-only
Default Value
0000 0000b = 00h (0mA)(3)
Serial Address
A2h = 1010001b
Byte Address
100 = 64h
This register is to be used in conjunction with ILDl to yield a sixteen-bit value. The values in ILDh:ILDl are in an un-
signed 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 sections.
Laser Diode Bias Current LSB (ILDl)

D[0]
read-only
Default Value
0000 0000b = 00h (0mA)
Serial Address
A2h = 1010001b
Byte Address
101 = 65h
Each LSB represents 2
A. This register is to be used in conjunction with ILDh to yield a sixteen-bit value. The values
in ILDh:ILDl 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. 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.

read-only
Default Value
0000 0000b = 00h (0mW)(5)
Serial Address
A2h = 1010001b
Byte Address
102 = 66h
Each LSB represents 25.6
W. This register is to be used in conjunction with TXOPl to yield a sixteen-bit value. The
values in TXOPh:TXOPl 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.
Transmitted Optical Power LSB (TXOPl)
D[7]
D[6]
D[5]
D[4]
D[3]
D[2]
D[1]
D[0]
read-only
Default Value
0000 0000b = 00h (0mW)
Serial Address
A2h = 1010001b
Byte Address
103 = 67h
Each LSB represents 0.1
W. This register is to be used in conjunction with TXOPh to yield a sixteen-bit value. The
values in TXOPh:TXOPl 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. 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 bitsection.
Notes:
3. ILDh will contain measured data after one A/D conversion cycle.
4. The scale factor corresponding to the sense resistor used must be set in the configuration register.
5. TXOPh will contain measured data after one A/D conversion cycle.
