Analog Configuration Bits for P1.7–P1.0 (respectively).
Port pins configured for analog mode have their weak pull-up and digital receiver
disabled. For analog mode, the pin also needs to be configured for open-drain
mode in the P1MDOUT register.
0: Corresponding P1.n pin is configured for analog mode.
1: Corresponding P1.n pin is not configured for analog mode.
These bits are ignored if the corresponding bit in register P1MDIN is logic 0.
0: Corresponding P1.n Output is open-drain.
1: Corresponding P1.n Output is push-pull.
