LEGEND: R/W = Read/Write; W = Write only; -n = value after reset |
Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7 | CHA PDN | W | 0h | 0 = Normal operation
1 = Power-down channel A |
6 | CHB PDN | R/W | 0h | 0 = Normal operation
1 = Power-down channel B |
5 | CHC PDN | R/W | 0h | 0 = Normal operation
1 = Power-down channel C |
4 | CHD PDN | W | 0h | 0 = Normal operation
1 = Power-down channel D |
3 | STANDBY | R/W | 0h | The ADCs of both channels enter standby.
0 = Normal operation 1 = Standby |
2 | GLOBAL PDN | R/W | 0h | 0 = Normal operation
1 = Global power-down |
1 | 0 | W | 0h | Must write 0. |
0 | CONFIG PDN PIN | R/W | 0h | This bit configures the PDN pin as either a global power-down or standby pin.
0 = Logic high voltage on the PDN pin sends the device into global power-down 1 = Logic high voltage on the PDN pin sends the device into standby |
