GPIO Interrupts
GPIO Control Register Definitions
PS022517-0508
Table 12. Port Alternate Function Mapping (Continued)
Many of 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 interrupts generate an interrupt when any edge occurs (both rising
and falling). For more details on interrupts using the GPIO pins, see
Diagram
Four registers for each port provide access to GPIO control, input data, and output data.
Table 13
Control Registers together to provide access to sub-registers for Port configuration and
control.
