(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).
