Section 20 I/O Ports

This LSI has four ports: A, B, D, and F.

All port pins are multiplexed with other pin functions. The functions of the multiplex pins are

selected by means of the pin function controller (PFC).

Each port is provided with data registers for storing the pin data and port registers for reading the

states of the pins.
