20.4 Specifying Port Registers
20.4.1 Functioning P22 Pin (MD0: Output) as the Melody or Buzzer Output
To enable the melody or buzzer function, the applicable bit of each related port register needs to be set. See Chapter 15,
"Port 2" for detail about the port registers.
Set the P22MD bit (P2MOD register bit 0) to “1” for selecting the melody or buzzer output as the secondary function of
the P22.
Set the P22C1 bit (P2CON1 register bit 0) to “1” and the P22C0 bit (P2CON0 register bit 0) to “1” for selecting the P22
pin state mode to CMOS output.
Data of P22D bit (bit0 of P2D register) does not affect to the melody or buzzer function, so don’t care the data for the
function.
- : Bit that does not exist
* : Bit not related to the Melody function
** : Don’t care

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