<1> After reset release, the port mode is the input mode (Hi-Z).
<2> Externally pull up the pin to be used (on-chip pull-up resistor cannot be used).
<3> Set the output latch of the corresponding port to 1.
<4> Set the corresponding bit of the POMn register to 1 to set the N-ch open drain output (V
<5> Set the corresponding bit of the PMn register to the output mode (data I/O is possible in the output

mode).
At this time, the output data is high level, so the pin is in the Hi-Z state.
