GPIO Function Tab

The GPIO0, GPIO1, GPIO2 and GPIO3 pins on the ADS7953 can function as simple general purpose

inputs/outputs or as specialized control and monitor functions. The alarm function described in the

previous section is processed by GPIO0 and GPIO1. Refer to the data sheet for specific details on GPIO0

and GPIO1 options. GPIO2 can be used to configure the input range of the ADS7953 (2.5V max or 5.0V

max), and GPIO3 can be used as a power down input pin.
