NOTES: A. To minimize errors caused by noise at CS, the internal circuitry waits for a set up time plus two falling edges of the internal system
clock after CS
↓ before responding to control input signals. 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.

NOTES: A. The first I/O CLOCK must occur after the rising edge of EOC.
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.
