Digital Audio Output. The signal is the Digital Audio Output
which supplies the IEC-958 digital audio data.
Alternate function : HRST_ extension selection input during
power-on stage (PRST falling edge). A logical low input
indicates raw HRST_ is used. A logical high input indicates
extended HRST_ is used.
