16. OE is asynchronously controlled; all other inputs are synchronous to the rising clock edge.
17. The output is disabled (high-impedance state) by CE=V
18. Timing shown is for x18 bus matching; x9 bus matching is similar with 4 cycles between address inputs.
19. See table “Right Port Operation“ for data output on first and subsequent cycles.
20. CNTEN = V
