MITSUBISHI SOUND PROCESSORS
M61503FP
TONE CONTROL/VOLUME CONTROL
DESCRIPTION
The M61503FP is a sound controller IC with the "BBE sound" sound technology.
It can realize articulation of reconstruction sound by BBE surround built-in reproduce tone more
naturally.
(Note) This device is producted under license from BBE sound Lab,Inc.(USA) and
avilable to only licenses.

(2) NOTICE OF CONTROL DATA
1.Input only the control data at (1) INPUT DATA.
2.It's necessary to set up the all control data after poweron,although the internal circuit is forced as belows,when (VDDVSS)<3.3V(TYP).
=
3.The interval of data transmission from the microcontroller is over
0.1 sec.This is waiting time for soft-switching to reduce the
shocknoise.
