(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.
(4)Connect a decouple capacitor to GND
(5)3.3-V CMOS level input with internal pulldown, 5 V tolerant
(6)TTL Schmitt trigger, 5 V tolerant
