Initialization and Configuration
To use the GPIO, the peripheral clock must be enabled by setting the appropriate GPIO Port bit
field (GPIOn) in the RCGC2 register.
On reset, all GPIO pins (except for the five JTAG pins) are configured out of reset to be undriven
(tristate): GPIOAFSEL=0, GPIODEN=0, GPIOPDR=0, and GPIOPUR=0. Table 9-1 on page 174
shows all possible configurations of the GPIO pads and the control register settings required to
achieve them. Table 9-2 on page 174 shows how a rising edge interrupt would be configured for pin
2 of a GPIO port.
