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 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.

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 MIC3001, this register will always return zero.
This register is provided for compliance with SFF-8472. It is not used by the MIC3001 when doing threshold comparisons and
setting alarm or warning bits.

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 MIC3001, this register will always return
zero. This register is provided for compliance with SFF-8472. It is not used by the MIC3001 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.
