Note 41. I²C is a registered trademark of Philips Semiconductors.
Note 42. BICK rising edge must not occur at the same time as LRCK edge.
Note 43. CCLK rising edge must not occur at the same time as CSN edge.
Note 44. Data must be held long enough to bridge the 300ns-transition time of SCL.
Note 45. The AK4691 can be reset by the PDN pin = “L”.
Note 46. This is the count of LRCK “↑” from the PMADC1 or PMADC2 bit = “1”.
