GPIO Interrupts
GPIO Control Register Definitions
Many of the GPIO port pins can be used as interrupt sources. Some port pins can be con-
figured 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). See the
more information about interrupts using the GPIO pins.
Four registers for each port provide access to GPIO control, input data and output data.
Table 17 lists these port registers. Use the Port A–D Address and Control registers
together to provide access to subregisters for port configuration and control.
