If setting these pins in output mode and opening them, ports are in input mode until switched into
output mode by use of software after reset. Thus the voltage levels of the pins become unstable,
and there can be instances in which the power source current increases while the ports are in
input mode.
In view of an instance in which the contents of the direction registers change due to a runaway
generated by noise or other causes, setting the contents of the direction registers periodically by
use of software increases program reliability.
