Overview

Port 1 is an 8-bit I/O port. Port 1 pins also function as address bus output function, and as 8-bit

PWM output pins (PW7 to PW0). 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.
