GPIO Interrupts
GPIO Control Register Definitions
PS024314-0308
Many of the GPIO port pins are used as interrupt sources. Some port pins are
configured to generate an interrupt request on either the rising edge or falling edge of the
pin input signal. Other port pin interrupt sources generate an interrupt when any edge
occurs (both rising and falling). For more information about interrupts using the GPIO
pins, see
Four registers for each Port provide access to GPIO control, input data, and output data.
