Section 29 Pin Function Controller (PFC)
Section 29 Pin Function Controller (PFC)
29.1 Overview
The pin function controller (PFC) consists of registers to select the functions and I/O directions of
multiplexed pins. The pin functions and I/O directions can be individually selected for every pin
regardless of the LSI operating mode. Table 29.1 lists the multiplexed pins of this LSI.
The hatched entries in the table are the pin functions that are selected immediately after a reset.
Selection between the port function (function 4) and other functions (functions 1 to 3) are made in
the port control registers. For how to select a pin function for the pins on which two or more of
functions 1 to 3 are multiplexed, see the description of pin select registers (PSELA to PSELC) in
this section.
Note: The settings of the I/O buffer Hi-Z control registers A to F take priority over those of the
port control registers.
