Section 24 I/O Ports
Section 24 I/O Ports
This LSI has six ports: A to F.
All port pins are multiplexed with other pin functions. The functions of the multiplexed pins are
selected using the pin function controller (PFC).
Each port is provided with a data register for storing the pin data and a port read register for
reading out the pin values.
24.1 Port A
Port A is an I/O port with 32 pins shown in figure 24.1.
