Section 8 I/O Ports
8.9
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/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.
8.9.2
Table 8.17 summarizes the port 8 registers.
