PLHPF2CUT/ PLHPF2CUTB
This bit sets the cut-off frequency of HPF for reproduction. In the case of "0", HPF2CEL becomes effective for setting this bit.

This register controls the fading function of the analog volume.
AVFADE
It sets the fading function of the analog volume to ON/OFF.
AVFADE
Explanation
Fading function OFF
0
When a register set point of AVOL is just used for a real Volume
price and wants to do it and changes a value, setting of the
analog volume is updated immediately.
Fading function ON
1
When a register set point of AVOL was updated, a gain of the
analog volume changes by a +/-1 step towards a register set
point after the update in step time for AVFCON register setting.
AVMUTE
When this is set, mute becomes effective for the analog volume at the time of reproduction. It can control fading for the
mute shift by this bit by the analog volume forcibly by AVFADE.
AVMUTE
Explanation
0
As for the analog volume, a register set point of AVOL is effective.
At the time of re-start: The analog volume is set to MUTE.
1
It comes back to the setting Volume in AVOL by canceling it
because it writes it. This register level of AVOL cannot be
replaced by the setting of this bit.
