13) Input Selector and Input Gain
14) Constraints of serial control (BD3883FS)
15) Function setting while muting Volume (BD3883FS)
When changing Input Selector or Input Gain, the Soft-switching is not applied. Therefore, it is recommended to implement
the MUTE function.
MUTE setting example
On Soft-switching of the RECOUT, Surround, and Rear Volume functions, data must not be sent serially to the functions
before the switching operation is completed.
While muting Volume, to avoid increasing residual noise, set Bass, Middle and Treble to 0dB, Surround to OFF, and Rear
Volume to -10dB.

Direction
If the function for Soft-switch should serially send the data (Data(4)) on the
same Select Address, the time interval between the send operations must be
set to 500 -600msec.
