*: When these ports are used as general-purpose I/O port, each bit can be set individually for input or
output. However, each bit cannot be set individually for input or output even if 1bit or more bits are
used as address bus in same port.
All of general-purpose I/O ports except for port that used as address bus are operated as output
port.
Please be careful when using this setting.
