(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 have no direct connection with the internal DAC or ADC. See the
Interface #3
and
End-Points
sections.
(4)Connect a decoupling capacitor to GND.
(5)3.3-V CMOS level input with internal pulldown, 5 V tolerant
(6)TTL Schmitt trigger, 5-V tolerant
