Outputs L level when the output mode is
selected.
Outputs H level when the output mode is
selected.
Input mode (port input)
Output mode (port output)
The built-in pull-up resistor is not connec-
ted.
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 condi-
tions, setting to "1" does not make the
resistor connected.)
If the port is in the input mode, the contents
of the port are read. If not, "0" is read.
