Port 8

8.9.1

Overview

Port 8 is an 8-bit I/O port. Port 8 pins also function as SCI1 I/O pins (TxD1, RxD1, SCK1), the

IIC1 I/O pin (SCL1) (option in H8S/2138 Group only), HIF I/O pins (

CS2, GA20, HA0, HIFSD)

(H8S/2138 Group only), and external interrupt input pins (

IRQ5 to IRQ3). Port 8 pin functions are

the same in all operating modes. Figure 8.16 shows the port 8 pin configuration.
