8.9.1
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/2148 Group and H8S/2147N only), HIF I/O pins (CS2,
GA20, HA0, HIFSD) (H8S/2148 Group and H8S/2147N 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.
