(1) LV-TTL level
(2) 3.3-V CMOS level input
(3) 3.3-V CMOS level input with internal pulldown. This pin informs the PC of serviceable control signals such as mute, volume up, or volume down,
which has no connection with the internal DAC or ADC directly. See the Interface #3 and End-Points sections.
