Notes:
1. Calculated according to the BCLK frequency as follows:
0----.--5---x----1---0----9- – 60[ns]
f(BCLK)
2. Calculated according to the BCLK frequency as follows:
(---n-----+------0---.--5----)--x----1---0----9- – 60[ns] n is 1 for 1 wait setting, 2 for 2 waits setting and 3 for 3 waits setting.
f(BCLK)
3. Calculated according to the BCLK frequency as follows:
(---n-----–----0----.-5----)---x---1---0----9-- – 60[ns]
f(BCLK)
n is 2 for 2 waits setting, 3 for 3 waits setting.
