Byte address
MS byte (TXOPh): 102 = 66h
LS byte (TXOPl): 103 = 67h
Each LSB of TXOPh represents 25.6 μW, and each LS bit of TXOPl represents 0.1 μW. TXOPh is used in conjunction with
TXOPl to yield an unsigned sixteen-bit value.
In external calibration mode, the host should process the results using the appropriate slope and offset coefficients. TXOPh
contains the eight-bit ADC result and TXOPl is zero.
In internal calibration mode, the MIC3003’s ALU applies the coefficients stored in (TXSLPh:TXSLPl) and (TXOFFh:TXOFFl).
The TXOP registers will contain valid data after one ADC conversion cycle.
Notes:
3. ILDh will contain measured data after one A/D conversion cycle.
4. TXOPh will contain measured data after one A/D conversion cycle.

MS byte (RXOPh): 104 = 68h
LS byte (RXOPl): 105 = 69h
Each LSB of RXOPh represents 25.6 μW, and each LS bit of RXOPl represents 0.1 μW.RXOPh is used in conjunction with
RXOPl to yield an unsigned sixteen-bit value.
In external calibration mode, the host should process the results using the appropriate slope and offset coefficients. RXOPh
contains the twelve-bit ADC result and the lower four bits of RXOPl are zero.
In internal calibration mode, the MIC3003’s ALU applies the coefficients stored in (RXSLP[0-7]h:RXSLP[0-7]l) and
(RXOFF[0-7]h:RXOFFl[0-7]).
The RXOP registers will contain valid data after one ADC conversion cycle.
