PRELIMINARY
Notes:
46. FIFO1 Write (CSA = LOW, W/RA = HIGH, MBA = LOW), FIFO1 Read (CSB = LOW, MBB = LOW). Data in the FIFO1 output register has been read from
the FIFO.
47. D = Maximum FIFO Depth = 256 for the CY7C43626, 512 for the CY7C43636, 1K for the CY7C43646, 4K for the CY7C43666, and 16K for the CY7C43686.
48. If Port B size is word or byte, t
is referenced to the rising CLKB edge that writes the last word or byte of the long word, respectively.
49. t
is the minimum time between a rising CLKA edge and a rising CLKB edge for AFA to transition HIGH in the next CLKA cycle. If the time between the
rising CLKA edge and rising CLKB edge is less than t
, then AFA may transition HIGH one CLKB cycle later than shown.
50. If Port C size is word or byte, AFC is set LOW by the last word or byte write of the long word, respectively.
51. t
is the minimum time between a rising CLKC edge and a rising CLKA edge for AFC to transition HIGH in the next CLKC cycle. If the time between
the rising CLKC edge and rising CLKA edge is less than t
SKEW2
, then AFC may transition HIGH one CLKA cycle later than shown.
