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, 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.

NOTES:
1. tSKEW1 is the minimum time between a rising CLKA edge and a rising CLKC edge for
FFC to transition HIGH in the next CLKC cycle. If the time between the rising CLKA edge and rising
CLKC edge is less than tSKEW1, then
FFC may transition HIGH one CLKC cycle later than shown.
2. If Port C size is word or byte,
FFC is set LOW by the last word or byte write of the long word, respectively (the word-size case is shown).
