Notes:
55. FIFO1 Write (CSA = LOW, W/RA = HIGH, MBA = LOW), FIFO1 Read (CSB = LOW, RENB = HIGH, MBB = LOW). Data in the FIFO1 output register has been
read from the FIFO.
56. If Port B size is word or byte, AEB is set LOW by the last word or byte Read from FIFO1, respectively.
57. t
is the minimum time between a rising CLKA edge and a rising CLKB edge for AEB to transition HIGH in the next CLKB cycle. If the time between the
rising CLKA edge and rising CLKB edge is less than t
, then AEB may transition HIGH one CLKB cycle later than shown.
58. FIFO2 Write (MBC = LOW), FIFO2 Read (CSA = LOW, W/RA = LOW, MBA = LOW). Data in the FIFO2 output register has been read from the FIFO.
59. If Port C size is word or byte, t
is referenced to the rising CLKC edge that writes the last word or byte of the long word, respectively.
60. t
is the minimum time between a rising CLKC edge and a rising CLKA edge for AEA to transition HIGH in the next CLKA cycle. If the time between the
rising CLKC edge and rising CLKA edge is less than t
, then AEA may transition HIGH one CLKA cycle later than shown.
61. When FIFO is operated at the almost empty/full boundary, there may be an uncertainty of up to 2 clock cycles for flag deassertion, but the flag will always be
asserted exactly when the FIFO content reaches the programmed value. Use the assertion edge for trigger if flag accuracy is required. Refer to
