Note 22. Data must be held for sufficient time to bridge the 300 ns transition time of SCL.
Note 23. The AK4613 can be reset by setting the PDN pin to “L” upon power-up.
Note 24. These cycles are the numbers of LRCK rising from the PDN pin rising.
Note 25. I²C is a registered trademark of Philips Semiconductors.
