Analog Configuration Bits for P0.7–P0.0 (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 P0MDOUT register.
0: Corresponding P0.n pin is configured for analog mode.
1: Corresponding P0.n pin is not configured for analog mode.
These bits are ignored if the corresponding bit in register P0MDIN is logic 0.
0: Corresponding P0.n Output is open-drain.
1: Corresponding P0.n Output is push-pull.
