Product Specification

GPIO Interrupts

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 “Interrupt Controller” on page 46 for more

information about interrupts using the GPIO pins.

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.
