GPIO controller
A total of 24 GPIOs are available in the STMPE2403 port expander IC. 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.
