Analog Configuration Bits for P4.7–P4.0 (respectively).
Port pins configured for analog mode have their weak pullup, digital driver, and
digital receiver disabled.
0: Corresponding P4.n pin is configured for analog mode.
1: Corresponding P4.n pin is not configured for analog mode.
These bits are ignored if the corresponding bit in register P4MDIN is logic 0.
0: Corresponding P4.n Output is open-drain.
1: Corresponding P4.n Output is push-pull.
