Note 4: Self mute circuit is included on chip and is in independent from I
2C bus stage.
Self mute operating voltage is VCC = 7.8 V
Note 5: Auto Increment is available.
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:
Sub address byte 1
→ byte 1 writing → Sub address byte 2 → byte 2 writing: available
Sub address byte 1
→ byte 1 writing ---------------------------- → byte 2 writing: available
