8.6.1
Port 5 is a 3-bit I/O port. Port 5 pins also function as SCI0 I/O pins (TxD0, RxD0, SCK0), and the
IIC0 I/O pin (SCL0) (option in H8S/2148 Group and H8S/2147N only). In the H8S/2148 Group
and H8S/2147N, P52 and SCK0 are NMOS push-pull outputs, and SCL0 is an NMOS open-drain
output. Port 5 pin functions are the same in all operating modes.
Figure 8.13 shows the port 5 pin configuration.
