Table 68. IO_CONTROL_1 Register Bit Descriptions (Continued)

Bits

Bit Name

Description

GPIO_CTRL1

Digital Output P1 enable. When GPIO_CTRL1 is set, the digital output P1 is active. When GPIO_CTRL1 is cleared, the pin

functions as analog input pin AIN2.

PDSW

Bridge power-down switch control bit. Set this bit to close the bridge power-down switch PDSW to AGND. The switch can sink up

to 30 mA. Clear this bit to open the bridge power-down switch. When the ADC is placed in standby mode, the bridge power-down

switch remains active.

This bit must be programmed with a Logic 0 for correct operation.
