NOTES:
1. Calculated according to the BCLK frequency as follows:
2. Calculated according to the BCLK frequency as follows:
n is ”2” for 1-wait setting, “3” for 2-wait setting and “4” for 3-wait setting.
3. Calculated according to the BCLK frequency as follows:
n is “2” for 2-wait setting, “3” for 3-wait setting.
