Figure 15. Timing for 16-Clock Transfer Not Using CS With MSB First
NOTE A: To minimize errors caused by noise at CS, the internal circuitry waits for a setup time after CS
↓ before responding to control input signals.
Therefore, no attempt should be made to clock in an address until the minimum CS setup time has elapsed.
