Section 17 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 17.1 to 17.12
list the multiplexed pins of this LSI.
Tables 17.13 and 17.14 list the pin functions in each operating mode.
