4:0 P2MDOUT[4:0] _{Output Configuration Bits for P2.4–P2.0 (respectively).}
These bits are ignored if the corresponding bit in register P2MDIN is logic 0.
0: Corresponding P2.n Output is open-drain.
1: Corresponding P2.n Output is push-pull.
Note: P2.0 is not available for analog input in the QFN20-packaged devices, and P2.1-P2.4 are only available in the
QFN24-packaged devices.

3:0 P2SKIP[3:0] _{Port 2 Crossbar Skip Enable Bits.}
These bits select Port 2 pins to be skipped by the Crossbar Decoder. Port pins
used for analog, special functions or GPIO should be skipped by the Crossbar.
0: Corresponding P2.n pin is not skipped by the Crossbar.
1: Corresponding P2.n pin is skipped by the Crossbar.
Note: P2.0 is not available for crossbar peripherals in the QFN20-packaged devices, and P2.1-P2.4 are only
available in the QFN24-packaged devices.
