Read = 0000000b; Write = Don’t Care.
Analog Configuration Bits for P3.0.
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 P3MDOUT register.
0: Corresponding P3.n pin is configured for analog mode.
1: Corresponding P3.n pin is not configured for analog mode.
Read = 0000000b; Write = Don’t Care.
These bits are ignored if the corresponding bit in register P3MDIN is logic 0.
0: Corresponding P3.n Output is open-drain.
1: Corresponding P3.n Output is push-pull.
