The Setup time is determined by the value programmed into the
Setup Timing
register, index 3Ah/3Dh. Using the Timer
Set 0 default value of 01h, the setup time would be 70 ns. S = (N

For typical active timing programmed at 280 ns, maximum -WAIT timing is 190 ns after Command active.

-IOIS16 must go low within 3Tcp + 10 ns of the cycle beginning or -IOIS16 will be ignored and -CE will not be activated.
