NOTES:
1. A
2A
, A
1A
, and A
0A
all are held HIGH for FIFO access at Port A.
A
0B
is held HIGH for FIFO access at Port B.
2. Parameters without parentheses apply to FIFO #2 operation.
Parameters with parentheses apply to FIFO #1 operation.
3. Both assertion and deassertion of the Half-Full Flags are controlled
entirely by rising clock edges, rather than by falling clock edges.
4. t
SKEW2
is the minimum time between a falling CK
B
(CK
A
) edge
and a rising CK
A
(CK
B
) edge for HF to change predictably during
the current clock cycle. If the time between the falling edge of
CK
B
(CK
A
) and the rising edge of CK
A
(CK
B
) is less than t
SKEW2
,
then it is not guaranteed that HF will change state until the next
following CK
A
(CK
B
) edge.
