the function.
- P20(Port2) is an output-only port, does not have an register to select the data direction(input or output).
- The output characteristics of port22 corresponds to VOL1 and VOH1 when P22MD bit is “1”
(melody/buzzer is selected as the 2
“0”, which are shown in Appendix C, "Electrical Characteristics".
See Chapter 18, “Port 2” for detail about the port registers.
22.4.1
the P22 as CMOS output.
Note:
When you want to make sure the Melody/Buzzer function is working, please check related port registers are specified.
Set P22MD bit (bit0 of P2MOD register) to “1” for specifying the melody or buzzer output as the secondary function
Set P22C1 bit (bit０ of P2CON1 register) to “1” and set P22C0 bit(bit０ of P2CON0 register) to “1”, for specifying
Data of P２０D bit (bit０ of P2D register) does not affect to the melody or buzzer function, so don’t care the data for
