TONE CONTROL/VOLUME CONTROL

MITSUBISHI ELECTRIC  

(2) NOTICE OF CONTROL DATA

1.use only the control data of (1) INPUT DATA .

2.The interval of data transmission from the microcontroller is over

0.1 sec.: This is the waiting time for the "soft-switching"

to reduce the shock noise.

(The "soft-switching " is available at the volume and

QXpander.)

=

<NOTE>

(1) The "Slot1" and the "Slot2" are independent data.

Each data need each waiting time.

(2) The some function of the volume and other function

have no "Soft-Switching".

<Example 1>

When the volume is set as " infinitesimal", it's

immediately attenuated (but,it needs the waiting time

to reach the final attenuation).

<Example 2>

The change of tone control is immediately executed.

3.It's necessary to set the all control data after power-on,

although the internal circuit is forced as below,when (VDD-

VSS)<3.3V(TYP).
