Evaluating Performance with the ADCPro Software
10.1.6 PGA GPIO Tab
The PGA GPIO tab, as Figure 35 shows, allows for control of three of the GPIO pins (GPIO0-GPIO2) in
the PGA280. These pins can be independently used as GPIO inputs, GPIO outputs, and external MUX
mode. For each of these pins, select the desired function. If used as a GPIO output, a high or a low is
selected with the Output push button. If used as a GPIO input, the value is shown by the indicator light on
the right when the Read GPIO button is clicked.

Note that the control for setting the GPIO values in Mux mode is in the PGA Configuration tab, described
in
Section 10.1.5 .
The remaining four GPIO pins (GPIO3-GPIO6) are reserved in ECS mode to control the ADS1259.
