q
All of port options except the pull-up resistor option of Port 0 can be specified in bit units.
q
When the “CMOS output” is selected for port 0 as an output format, the pull-up resistor will be provided, and when the “n-
channel open-drain output” is selected, the pull-up resistor will not be provided.
q
Whichever the “CMOS” or the “n-channel open-drain” output format is selected, the programmable pull-up resistor will be
provided.
