Outputs L level when the
output mode is selected.
Outputs H level when the
output mode is selected.

The built-in pull-up resistor
is not connected.
The built-in pull-up resistor
is connected. (The resistor
is connected in the input
mode only. Under any oth-
er conditions, setting to "1"
does not make the resistor
connected.)
