16. Pin Function Controller (PFC)
Section 16 Pin Function Controller (PFC)
16.1 Overview
The pin function controller (PFC) is composed of registers for selecting the function of
multiplexed pins and the direction of input/output. Table 16.1 lists this LSI's multiplexed pins. The
multiplex pin functions have restrictions dependent on the operating mode. Table 16.2 lists the pin
functions and initial values for each operating mode.
