4. Microprocessor Interface timing applies to normal mode register accesses

only.

5. In non-multiplexed address/data bus architecture's, ALE should be held high,

parameters tSALR, tHALR, tVL, tHLR and tSLR are not applicable.

6. Parameter tHAR is not applicable if address latching is used.

7. When a set-up time is specified between an input and a clock, the set-up time

is the time in nanoseconds from the 1.4 Volt point of the input to the 1.4 Volt

point of the clock.

8. When a hold time is specified between an input and a clock, the hold time is

the time in nanoseconds from the 1.4 Volt point of the input to the 1.4 Volt

point of the clock.
