(CSB+WRB)
A valid write cycle is defined as a logical OR of the CSB and the WRB signals.
In non-multiplexed address/data bus architectures, ALE should be held high so parameters tS
tH
Parameter tH
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 V point of the input to the 1.4 V point of the clock.
When a hold time is specified between an input and a clock, the hold time is the time in nanoseconds
from the 1.4 V point of the input to the 1.4 V point of the clock.
