Signals listed on the External Bus Timing diagrams are described below.
External Bus Timing
TwWAIT
– If RDY_ENABLE=0, specifies the width of the chip select active period for the non-
– If RDY_ENABLE=1, specifies the wait time before the RDY_N line is first sampled
TrWAIT
– If RDY_ENABLE=0, specifies the width of the chip select active period for the non-
– If RDY_ENABLE=1, specifies the wait time before the RDY_N line is first sampled
burst-mode write cycle. The allowed range is 0–31, resulting in a wait time of 1–32
clocks.
for the write cycle. This provides a max wait time of 484 nS at 66 MHz. Anything
greater than this will require the external RDY_N line and external logic.
