P2MOD
P2 (Port 2) is an output-only pin and does not have the register to select the data direction(input or output).
The output characteristics of the P2 pins (P20, P21, P22, and P24) are VOL1 and VOH1 (described in "Appendix C
Electrical Characteristics") when each bit (P20MD, P21MD, P22MD, and P24MD) of the corresponding P2MOD
register is "1" (melody/buzzer is selected as the secondary function) and are VOL2 and VOH2 when each bit is "0".

P20MD (bit 0)
The P24MD bit is used to select the primary function or the secondary function of the P24 pin.
The P22MD bit is used to select the primary function or the secondary function of the P22 pin.
The P21MD bit is used to select the primary function or the secondary function of the P21 pin.
The P20MD bit is used to select the primary function or the secondary function of the P20 pin.
