GPIO Control Register Definitions
PS019921-0308
Table 12. 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). For more information on interrupts using the GPIO pins, see
Controller
Four registers for each Port provide access to GPIO control, input data, and output data.
