8.2.1
Port 1 is an 8-bit I/O port. Port 1 pins also function as address bus output pins (A7 to A0), and as
8-bit PWM output pins (PW7 to PW0) (H8S/2148 Group and H8S/2147N only). Port 1 functions
change according to the operating mode. Port 1 has a built-in MOS input pull-up function that can
be controlled by software.
Figure 8.1 shows the port 1 pin configuration.
