FFH (0dB) to 00H (MUTE). If the PDN pin goes to “L”, the ATTs are initialized to FFH. The ATT values are
FFH when RSTN = “0”. When RSTN return to “1”, the ATT values fade to their current value. This digital
attenuator is independent of the soft mute function.
The transition between set values is a soft transition of 7425 levels. It takes 7424/fs (168ms@fs=44.1kHz) from
0: DZF pin goes “H” at Zero Detection (default)
1: DZF pin goes “L” at Zero Detection
