8.10.1
Port 9 is an 8-bit I/O port. Port 9 pins also function as external interrupt input pins (IRQ0 to
IRQ2), the A/D converter external trigger input pin (ADTRG), host interface input pins (ECS2,
CS1, IOW, IOR) (H8S/2148 Group and H8S/2147N only), the IIC0 I/O pin (SDA0) (option in
H8S/2148 Group and H8S/2147N only), the subclock input pin (EXCL), bus control signal I/O
pins (AS/IOS, RD, HWR, LWR, WAIT), and the system clock ( ) output pin. In H8S/2148 Group
and H8S/2147N, P97 is an NMOS push-pull output. SDA0 is an NMOS open-drain output, and
has direct bus drive capability.
Figure 8.17 shows the port 9 pin configuration.
