Address = 19h

BIT 7 BIT 6 BIT 5 BIT 4 BIT 3 BIT 2 BIT 1 BIT 0

PD_WCTC PD_WCTB WCTB2 WCTB1 WCTB0 WCTC2 WCTC1 WCTC0

The WCT2 configuration register configures the device WCT circuit channel selection.

Bit 7 PD_WCTC: Power-down WCTC

0 = Powered down (default)

1 = Powered on

Bit 6 PD_WCTB: Power-down WCTB

0 = Powered down (default)

1 = Powered on
