GPIO Interrupts

Port
Port C
Note: Because there are at most two choices of alternate function for any pin of Port C, the Alternate
Function Set register AFS2 is implemented but not used to select the function. Also, alternate
function selection as described in “Port A–D Alternate Function Sub-Registers” on page 39 must
also be enabled.

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). Refer to the chapter
information about interrupts using the GPIO pins.
