Description
When in a input port state, setting the
corresponding bit to 1 turns on the input pull-up
MOS for that pin.
Description
When not specified for address output, setting a
PCODR bit to 1 makes the corresponding pin an
NMOS open-drain output pin, while clearing a
PCODR bit to 0 makes the corresponding pin a
CMOS output pin.
