Section 9 I/O Ports
9.2.4
P3ODR is an 8-bit readable/writable register that specifies the output type of port 3.
9.2.5
Port 3 pins also function as SCI_0 I/O pins and interrupt input pins. The correspondence between
the register specification and the pin functions is shown below.

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