This register selects single-ended or pseudo-differential operation for any analog input channels that are not configured as pairs (see the AIN_CFG register). Depending on the contents of this register, AIN-COM must be connected to either GND or REFby2 on the PCB.
|7-1||0||R||000 0000b||Reserved bits. Reads return 000 0000b.|
|0||COM_CFG||R/W||0b||This bit selects the analog input channel configuration when = 00b or 11b in the AIN_CFG register:
0b = All individual channels are single-ended inputs; connect the AIN-COM pin to GND
1b = All individual channels are pseudo-differential inputs; connect the AIN-COM pin to REFby2
