System Control & Configuration
Port 3
If this 15-bit port is used for general purpose I/O, the direction of each line can be
configured via the corresponding direction register DP3. All port lines can be switched
into push/pull or open drain mode via the open drain control register ODP3. Due to pin
limitations register bit P3.14 is not connected to any pin.
