Notes
* 39. It is measured from BICK “↓” when the BICK polarity is inverted by setting BCKPx bit = “1”.
* 40. It is measured from BICK “↑” when the BICK polarity is inverted by setting BCKPx bit = “1”.
* 41. Set SDOPHx bit to “1” and the data from SDOUTx pin is output based on BICK “↑” when BICK
speed is more than 12.288MHz such as when using TDM256 mode with 96kHz sampling
frequency or TDM128 mode with 192kHz sampling frequency in slave mode. SDOPHx bit must be
set to “0” in master mode. 018011601-E-00-PB 2018/09
