Note 39. It is measured from BICK “↓” when the BICK polarity is inverted by setting BCKPx bit = “1”.
Note 40. It is measured from BICK “↑” when the BICK polarity is inverted by setting BCKPx bit = “1”.
Note 41. Set SDOPHx bit to “1” and the data from SDOUTx pin should be output based on BICK “↑”
when BICKx speed is more than 12.288MHz such as TDM512 mode with 48kHz sampling
frequency, 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.
