Notes:
1. Calculated according to the BCLK frequency as follows:
0----.-5----×_{-----1---0----}⁹ _{– 10[ns]}
f_(BCLK)
2. Calculated according to the BCLK frequency as follows:
-⁽--ⁿ----–-----0---.-5----⁾---^×-----1---0---⁹- – 40[ns] n is 2 for 2-wait setting, 3 for 3-wait setting.
f_(BCLK)
3. Calculated according to the BCLK frequency as follows:
0----.-5----×_{-----1---0----}⁹ _{– 25[ns]}
f_(BCLK)
4. Calculated according to the BCLK frequency as follows:
0----.-5----×_{-----1---0----}⁹ _{– 15[ns]}
f_(BCLK)
5. When using multiplex bus, set f_(BCLK) 12.5 MHz or less.
6. Calculated according to the BCLK frequency as follows: ^{0----.-5----×}-----1---0----⁹ – 20[ns]
