Sensor Driver Voltage Selection Register (Address 0x22/0x32)

The 0x32 command sets the transmitter output AC voltage (TXV). At power-up, TXV defaults to 0x00.

The 0x22 command is used to read the current value of TXV. TXF1 and TXF2 diagnostic bits are not

valid when TXV=0x00 or TXV=0x03.

MUX Control Register (Address 0x23/0x33)

The 0x33 command controls the ten 3-channel MUXES connected to the SENx pins. It also controls

the 2-channel MUX connected to the VAR_SEN pin. The 0x23 command reads the current data in the

channel select control register.
