SDA goes to “Hi-Z” during initial reset.
Initial reset for headphone search is determined by the state of HDT
When HDT = “H”, STO = “L”
When HDT = “L”, STO = “H”
The output in initial reset is “H”
S/PDIF data is output when SELTX [1:0] bit= “00”. “L” during initial rest.
Connect to GND.
This pin must be connected to DVDD.
