NOTES:
1. tSKEW2 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 tSKEW2, then
AEB may transition HIGH one CLKB cycle later than shown.
2. FIFO1 Write (
CSA = LOW, W/RA = LOW, MBA = LOW), FIFO1 read (CSB = LOW, W/RB = HIGH, MBB = LOW). Data in the FIFO1 output register has been read from the FIFO.
3. If Port B size is word or byte,
AEB is set LOW by the last word or byte read from FIFO1, respectively.

AEA to transition HIGH in the next CLKA cycle. If the time between the rising CLKB edge
and rising CLKA edge is less than tSKEW2, then
AEA may transition HIGH one CLKA cycle later than shown.
2. FIFO2 Write (
CSB = LOW, W/RB = LOW, MBB = LOW), FIFO2 read (CSA = LOW, W/RA = LOW, MBA = LOW). Data in the FIFO2 output register has been read from the FIFO.
3. If Port B size is word or byte, tSKEW2 is referenced to the rising CLKB edge that writes the last word or byte of the long word, respectively.

AFA to transition HIGH in the next CLKA cycle. If the time between the rising CLKA edge

2. FIFO1 Write (
CSA = LOW, W/RA = HIGH, MBA = LOW), FIFO1 read (CSB = LOW, W/RB = HIGH, MBB = LOW). Data in the FIFO1 output register has been read from the FIFO.
3. D = Maximum FIFO Depth = 256 for the IDT723624, 512 for the IDT723634, 1,024 for the IDT723644.
4. If Port B size is word or byte, tSKEW2 is referenced to the rising CLKB edge that reads the last word or byte of the long word, respectively.
