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