NOTES:
1. Timing measurements are referenced to and from a low voltage of 0.2 VDD and a high voltage of 0.8 VDD,
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 0.2 V
DD
and 0.8 VDD.
2. Because of loading variations, RWB may be valid after ASB even though both are initiated by the rising edge
of S2 (specification #20A).
