1. Timing measuremenll are referenced to and from a low voltage of 0.8 volt and a high voltage of 2.0 volts, unless otherwise
noted. The voltage swing through this range should start oullide and pass through the range such that the rise or fall is linear
between 0.8 volt and 2.0 volts.
2. Because of loadng variations, R/W may be valid
after
AS even though both are initiated by the rising
edge
of S2 (specification
#20A).
