PARAMETER MEASUREMENT INFORMATION (continued)
A.
To minimize errors caused by noise at CS, the internal circuitry waits for a setup time plus two falling edges of the
internal system clock 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.
B.
A low-to-high transition of CS disables ADDRESS and the I/O CLOCK within a maximum of a setup time plus two
falling edges of the internal system clock.
