Default Value

Byte address
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.
