Note 25. I2C-bus is a trademark of NXP B.V.
Note 26. CCLK rising edge must not occur at the same time as CSN edge.
Note 27. RL = 1kΩ/10% change ( Pull-up to DVDD)
Note 28. Data must be held long enough to bridge the 300ns-transition time of SCL.
Note 29. The AK4636 can be reset by the PDN pin = “L”
Note 30. This is the count of FCK “↑” from the PMADC = “1”.
