The Device Configuration page configures the GPIO and general settings that the ADS7953 ADC offers. The ADS7953 device has four GPIO pins that can be independently configured for various functions, such as general-purpose input (GPI), general-purpose output (GPO), power-down input, device range input, and alarm thresholds. Not all GPIOs are capable of each function. See the GPIO Registers section in the ADS7953 data sheet for additional details. These GPIO functions can be selected using drop-down menus. The GPIO direction can also be configured as an input or output. These GPIO settings are programmed to the ADC by clicking on the button shown in Figure 6-6.

The general settings shown in Figure 6-6 can also be configured in this page. If a GPIO is configured as a GPO, then the output can be user controlled as either a logic 0 or 1. Below the general settings are four visual GPIO alerts that illuminate when the GPI input value is equal to a logic 1.
