PRELIMINARY
Notes:
27. If Port B size is word or byte, EFB is set LOW by the last word or byte read from FIFO1, respectively.
28. t
is the minimum time between a rising CLKA edge and a rising CLKB edge for EFB to transition HIGH in the next CLKB cycle. If the time between
the rising CLKA edge and rising CLKB edge is less than t
SKEW1
, then the transition of EFB HIGH may occur one CLKB cycle later than shown.
