When PDN pin goes “ L” , the registers are initialized to their default values.
When RSTN bit goes “ 0” , the only internal timing is reset and the registers are not initialized to their default

Master clock frequency is detected automatically at ACKS bit “ 1” . In this case, the setting of CKS2-0

The transition between set values is soft transition of 7425 levels. It takes 7424/fs ([email protected]=44.1kHz) from
FFH (0dB) to 00H (MUTE). If PDN pin goes to “ L” , the ATTs are initialized to FFH. The ATTs are FFH when
RSTN = “ 0” . When RSTN return to “ 1” , the ATTs fade to their current value. This digital attenuator is
independent of soft mute function.
