General-Purpose Input/Output (GPIO)
The GPIO peripheral provides dedicated general-purpose pins that can be configured as either inputs or
outputs. When configured as an output, you can write to an internal register to control the state driven on
the output pin. When configured as an input, you can detect the state of the input by reading the state of
an internal register. This chapter describes the GPIO.
