Section 18   Pin Function Controller

The pin function controller (PFC) is composed of registers for selecting the function of
multiplexed pins and the input/output direction. The pin function and input/output direction can be
selected for each pin individually without regard to the operating mode of the chip. Table 18.1
lists the multiplexed pins.
