Description
When a pin is specified as an input port, setting the
corresponding bit to 1 turns on the MOS input pull-
up for that pin.
9.6.5 Port C Open-Drain Control Register (PCODR)
PCODR is an 8-bit read/write register that specifies an output type of port C.

Description
When a pin is specified as an output port, setting
the corresponding bit to 1 specifies pin output as
open-drain and the MOS input pull-up to the off
state. Clearing this bit to 0 specifies push-pull
output.
