Flag Timing and First Available Write when the FIFO is Full
NOTES:
1. t
SKEW1
is the mnimumtime between a rising CLKB edge and a rising CLKA edge for
EF
to transition HIGH in the next CLKA cycle. If the time between the rising CLKB edge
and rising CLKA edge is less than t
SKEW1
, then the transition of
EF
HIGH may occur one CLKA cycle later than shown.
2. Port B size of long word is selected for the FIFO read by SIZ1 = LOW, SIZ0 = LOW. If port B size is word or byte, t
SKEW1
is referenced fromthe rising CLKB edge that reads
the last word or byte of the long word, respectively.

NOTES:
1. t
SKEW2
is the mnimumtime between a rising CLKA edge and a rising CLKB edge for
AE
to transition HIGH in the next CLKB cycle. If the time between the rising CLKA edge
and rising CLKB edge is less than t
SKEW2
, then AE may transition HIGH one CLKB cycle later than shown.
2. FIFO write (

A = HIGH, MBA = LOW), FIFO read (

B = LOW, MBB = LOW).
3. Port B size of long word is selected for the FIFO read by SIZ1 = LOW, SIZ0 = LOW. If port B size is word or byte, t
SKEW2
is referenced to the last word or byte of the long
word, respectively.
