14.2.2 Peripheral Pin Select (PPS) Overview

The PPS feature allows remapping of pin and port functions and can be configured to best suit an application. This simplifies board design and allows peripherals to be connected to one another with or without a pin.

Figure 14-3 shows the structure of a remappable input. The control logic is based on the peripheral, through selection of which Remappable Pin (RPn) is used as the input source. Each peripheral is associated with a register bit field to select RPn. More than one peripheral can select the same input pin.

Figure 14-4 shows the structure of a remappable output. Unlike the inputs, the control logic is based on the remappable pin. Each RPn pin has an associated register bit field to select which peripheral output is routed to the pin. The output of one peripheral can be mapped to multiple RPn pins.
