to output mode by a program. The voltage level of these pins may be undefined and the power
current may increase while the ports remain in input mode.
The content of the direction registers may change due to noise or program runaway caused by
noise. In order to enhance program reliability, the program should periodically repeat the setting of
the direction registers.
