Note 1: The timing parameters in this table are guaranteed by design (GBD).

Note 2: The input/output timing reference level for all signals is V

/2.

Note 3: In a nonmux cycle, the timing reference refers only to the DSB signal. While in a mux cycle, the timing reference refers only to the

ASB signal.
