7:0 P4MDIN[3:0] Analog Configuration Bits for P4.7–P4.0 (respectively).
Port pins configured for analog mode have their weak pullup and digital receiver
disabled. The digital driver is not explicitly disabled.
0: Corresponding P4.n pin is configured for analog mode.
1: Corresponding P4.n pin is not configured for analog mode.

Function
7:0 P4MDOUT[7:0] Output Configuration Bits for P4.7–P4.0 (respectively).
These bits control the digital driver even when 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.
