GPIO Interrupts
GPIO Control Register Definitions
PS017609-0803
Table 11. Port Alternate Function Mapping (Continued)
Many of the GPIO port pins can be used as interrupt sources. Some port pins may be con-
figured to generate an interrupt request on either the rising edge or falling edge of the pin
input signal. Other port pin interrupts generate an interrupt when any edge occurs (both
rising and falling). Refer to the Interrupt Controller chapter for more information on
interrupts using the GPIO pins.
Four registers for each Port provide access to GPIO control, input data, and output data.
Table 12 lists these Port registers. Use the Port A-H Address and Control registers together
to provide access to sub-registers for Port configuration and control.
