A2h
MSB (VINh): 98 = 62h
LSB (VINl): 99 = 63h
Each LSB of VINh represents 25.6mV. VINh register is to be used in conjunction with VINl to yield a sixteen-bit value. The
values in VINh:VlNl 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 MIC3002, VINl will always return
zero. It is provided for compliance with SFF-8472.
Notes:
1. TEMPh will contain measured temperature data after the completion of one conversion.
2. VINh will contain measured data after one A/D conversion cycle.

ILDh is to be used in conjunction with ILDl 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 sections. In the MIC3002, ILDl will always return zero. It is provided for compliance with SFF-8472.

MSB (TXOPh): 102 = 66h
LSB (TXOPl): 103 = 67h
Each LSB of TXOPh represents 25.6µW. THOPh 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. In the MIC3002, this TXOPl will
always return zero. It is provided for compliance with SFF-8472.
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.
