Sub address
Control byte1 (01H) : Initial statement = All “0”
Control byte2 (02H) : Initial statement = All “0”
Self mute operating voltage is V
If control byte 1 is chosen by sub address, it is not necessary to send byte 2 in cases when both byte 1 and
2 are to be written.
Ex) In case of sub address = byte1 chosen:
