1.10 GPIO Module

The GPIO module allows the multifunction I/O pins to be configured and controlled as general-purpose digital inputs or outputs.

When configured for GPIO operation, the pins may be used as digital inputs or digital outputs.

When configured as an output, the GPIO state can be controlled and can also be configured for open-drain operation.

When configured as an input, the logical state of the pin can be read. The internal pull-up resistor for the input pin can be enabled or disabled.

These GPIO operations can be performed using GPIO Interface commands.
