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/2138 Group only). Port 1 functions change according
to the operating mode. Port 1 has an on-chip MOS input pull-up function that can be controlled by
software.
Figure 8.1 shows the port 1 pin configuration.
