8.3 Port 2
8.3.1 Overview
Port 2 is an 8-bit I/O port. Port 2 pins also function as address bus output function, 8-bit PWM
output pins (PW15 to PW8), and the timer connection output pin (CBLANK). Port 2 functions
change according to the operating mode. Port 2 has a built-in MOS input pull-up function that can
be controlled by software.
Figure 8.5 shows the port 2 pin configuration.
