Notes:
1. Calculated according to the BCLK frequency as follows:
0----.-5----×_{-----1---0----}⁹ _{– 60[ns]}
f_(BCLK)
2. Calculated according to the BCLK frequency as follows:
-⁽--ⁿ----+-----0---.--5---⁾----^×-----1---0---⁹- – 60[ns] 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----⁾---^×-----1---0---⁹- – 60[ns] n is 2 for 2 waits setting, 3 for 3 waits setting.
