Section 15 Pin Function Controller (PFC)
The pin function controller (PFC) is composed of registers that are used to select the functions of
multiplexed pins and assign pins to be inputs or outputs. Tables 15.1 and 15.2 list the multiplexed
pins of this LSI.
Tables 15.3 and 15.4 list the pin functions in each operating mode.
