NOTES: 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 the I/O CLOCK. No attempt should be made to clock out the data until the minimum CS setup
time has elapsed.
B. A low-to-high transition of CS disables I/O CLOCK within a maximum of a setup time plus two falling edges of the internal system
clock.
C. The first I/O CLOCK must occur after the end of the previous conversion.
