Section 8 I/O Ports
8.12
8.12.1
Port B is an 8-bit I/O port. Port B pins also have HIF input/output pins (CS3, CS4, HIRQ3,
HIRQ4) (H8S/2148 Group and H8S/2147N only), and a data bus input/output function (as D7 to
D0). The pin functions depend on the operating mode.
Figure 8.19 shows the port B pin configuration.
