(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 s.

: 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”.

Example1:

When the volume is set as “infinitesimal”, it’s immediately attenuated (but, it needs the waiting time to reach

the final attenuation).

Example2:

The change of tone control is immediately executed.

3. It is necessary to set the all control data after power-on, although the internal circuit is forced as below, when

(VDD-VSS) ≤ 3.3 V (Typ).
