C-MOS output
Open drain output
The built-in pull-up resistor is not connected.
The built-in pull-up resistor is connected. (The resistor is connected only when the port is used in the input mode or
as the open drain output. Under any other conditions, setting to "1" does not make the resistor connected.)
If the port is used in the input mode or as the open drain output, the contents of the port are read. If not, "0" is read.
