Section 22 Pin Function Controller (PFC)
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 22.1
lists the multiplexed pins.
