GPIO controller

A total of 16 GPIOs are available in the STMPE16M31PX. Most of the GPIOs are sharing

physical pins with some alternate functions. The GPIO controller contains the registers that

allow the host system to configure each of the pins into either a GPIO, or one of the

alternate functions. Unused GPIOs should be configured as outputs to minimize the power

consumption.
