Notes:
1. Calculated according to the BCLK frequency as follows:
0----.--5---x----1---0----9- _{– 45[ns]}
f_(BCLK)
2. Calculated according to the BCLK frequency as follows:
(_---n-----+_{-----0----.-5----})_---x_{----1---0---9-- – 45[ns]}
f_(BCLK)
n is 1 for 1 wait setting, 2 for 2 waits setting and 3 for 3 waits setting.
3. Calculated according to the BCLK frequency as follows:
(_---n-----–_{----0----.-5----})_---x_{---1----0---9-- – 45[ns]}
f_(BCLK)
n is 2 for 2 waits setting, and 3 for 3 waits setting.
