A2h
MS byte (TEMPh): 96 = 60h
LS byte (TEMPl): 97 = 61h
Each LS bit of TEMPh represents one degree Celsius. The TEMPh register is to be used in conjunction with the most
significant bit of TEMPl to yield an eight-bit or nine-bit signed (two’s complement) temperature value.
If OEMCFG6 bit 1 is set to zero, temperature is read to 1 °C resolution in TEMPh only, and TEMPl is zero.
If OEMCFG6 bit 1 is set to one, then temperature is read to 0.5 °C resolution as a nine-bit value consisting of TEMPh and the
MS bit of TEMPl. The lower seven bits of TEMPl are zero.
TEMPh will contain measured temperature data after the completion of one conversion.

A2h
MS byte (VINh): 98 = 62h
LS byte (VINl): 99 = 63h
Each LSB of VINh represents 25.6 mV, and each LS bit of VINl represents 0.1 mV. VINh is used in conjunction with VINl to
yield an unsigned sixteen-bit value.
In external calibration mode, the host should process the results using the appropriate slope and offset coefficients. VINh
contains the eight-bit ADC result and VINl is zero.
In internal calibration mode, the MIC3003’s ALU applies the coefficients stored in (VSLPh:VSLPl) and (VOFFh:VOFFl).
The VIN registers will contain valid data after one ADC conversion cycle.
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.

MS byte (ILDh):100 = 64h
LS byte (ILDl):101 = 65h
Each LSB of ILDh represents 512 μ A, and each LS bit of ILDl represents 2 μ A. ILDh is used in conjunction with ILDl to yield an
unsigned sixteen-bit value.
In external calibration mode, the host should process the results using the appropriate slope and offset coefficients. ILDh
contains the eight-bit ADC result and ILDl is zero.
In internal calibration mode, the MIC3003’s ALU applies the coefficients stored in (ISLPh:ISLPl) and (IOFFh:IOFFl).
The ILD registers will contain valid data after one ADC conversion cycle.
