PRODUCTION DATA.
This register configures the power mode, PGA gain, and multiplexer settings for the channels; see the Input Multiplexer section for details. CHnSET are similar to CH1SET, corresponding to the respective channels (see Table 10).

Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7 | PDn | R/W | 0h | Power-down (n = individual channel number).
This bit determines the channel power mode for the corresponding channel. 0 = Normal operation 1 = Channel power-down |
6-4 | GAINn[2:0] | R/W | 1h | PGA gain (n = individual channel number).
These bits determine the PGA gain setting. 000 = Do not use 001 = 1 010 = 2 011 = Do not use 100 = 4 101 = 8 110 = 12 111 = Do not use |
3 | Reserved | R/W | 0h | Reserved.
Must be set to 0. This bit reads low. |
2-0 | MUXn[2:0] | R/W | 0h | Channel input (n = individual channel number).
These bits determine the channel input selection. 000 = Normal input 001 = Input shorted to (AVDD + AVSS) / 2 (for offset or noise measurements) 010 = Do not use 011 = MVDD for supply measurement 100 = Temperature sensor 101 = Test signal 110 = Do not use 111 = Do not use |
