Notes:
1. H = High Voltage Level
L = Low Voltage Level
X = Dont Care or Irrelevant
↑= LOW-to-HIGH Transition
Z = High Impedance
2. A-to-B data flow shown. B-to-A flow control
is the same, except using xCEBA, xCLKBA,
and xOEBA.
3. Level of B before the indicated steady-state
input conditions were established.
