aVF_CH6 aVL_CH5 aVR_CH7 aVR_CH4 PD_WCTA WCTA2 WCTA1 WCTA0

The WCT1 control register configures the device WCT circuit channel selection and the augmented leads.

Bit 7 aVF_CH6: Enable (WCTA + WCTB)/2 to the negative input of channel 6 (ADS1296/8/6R/8R)

0 = Disabled (default)

1 = Enabled

Bit 6 aVL_CH5: Enable (WCTA + WCTC)/2 to the negative input of channel 5 (ADS1296/8/6R/8R)

0 = Disabled (default)

1 = Enabled

Bit 5 aVR_CH7: Enable (WCTB + WCTC)/2 to the negative input of channel 7 (ADS1298/8R)

0 = Disabled (default)

1 = Enabled

Bit 4 aVR_CH4: Enable (WCTB + WCTC)/2 to the negative input of channel 4

0 = Disabled (default)

1 = Enabled

Bit 3 PD_WCTA: Power-down WCTA

0 = Powered down (default)

1 = Powered on

Bits[2:0] WCTA[2:0]: WCT amplifier A channel selection; typically connected to RA electrode.

These bits select one of the eight electrode inputs of channels 1 to 4.

000 = Channel 1 positive input connected to WCTA amplifier (default)

001 = Channel 1 negative input connected to WCTA amplifier

010 = Channel 2 positive input connected to WCTA amplifier

011 = Channel 2 negative input connected to WCTA amplifier

100 = Channel 3 positive input connected to WCTA amplifier

101 = Channel 3 negative input connected to WCTA amplifier

110 = Channel 4 positive input connected to WCTA amplifier

111 = Channel 4 negative input connected to WCTA amplifier
