6.13.4 HP/Speaker De-emphasis
6.13.5 Digital Soft Ramp
6.13.6 Digital Zero Cross
Configures a 15µs/50µs digital de-emphasis filter response on the headphone/line and speaker outputs
Configures an incremental volume ramp from the current level to the new level at the specified rate.
Notes:
1. When the DIGSFT bit is enabled, the Master Volume (MSTxVOL[7:0]) transitions are guaranteed to
Configures when the signal level changes occur for the digital volume controls.
Notes:
1. If the signal does not encounter a zero crossing, the requested volume change will occur after a
2. The zero cross function is independently monitored and implemented for each channel.
