Section 20 I/O Ports
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.
20.1 Port A
Port A is an input/output port with the 26 pins shown in figure 20.1.
