6.3.1 Multiplexer

The ADC810-Q1 contains an input multiplexer that can track whether a pin is set as an analog pin or a digital pin. The Pin Function register configures the multiplexer register. If a pin is to be an analog pin, the pin will connect to the ADC and can be used to analyze analog signals. The selected channel can be configured by bits MUX[2:0] in the ADC Configuration register.

If set to a digital pin, the pin will be connected to the GPIO module. When an I/O is configured as an input, the pin is left at a high-impedance input. Electrostatic discharge (ESD) diodes connected to VDD and GND protect the ADC810-Q1 inputs. For IO8 and IO9, the analog mode is not available. Instead, the pins are set to their respective Alert functionality (ALERT/RDY and INT, respectively). The pins can be set as digital pins, however.
