11.4.8 Peripheral Multiplexing

When a peripheral is enabled, the associated pin output drivers are typically module controlled, while a few are user-settable. The I/O pin may be read through the input data path, but the output driver for the I/O port bit is generally disabled.

Note: Some ports are shared with analog module pins. The corresponding bits in the ANSELx registers, if present, must be set to ‘0’ for I/O port functionality.
