In PIC32 pin-controller is a combined gpio-controller, pin-mux and pin-config module. Remappable peripherals are assigned pins through per-pin based muxing logic. And pin configuration are performed on specific port registers which are shared along with gpio controller. Note, non-remappable peripherals have default pins assigned thus require no muxing.
