12.6 - Port 3
If this 15-bit port is used for general purpose I/O,
the direction of each line can be configured by the
corresponding direction register DP3. Most port
lines can be switched into push-pull or open drain

(pins P3.15, P3.14 and P3.12 do not support open
drain mode).
Due to pin limitations register bit P3.14 is not
connected to an output pin.
