NOTES:
1. t
RSS
and t
RSH
need not be met unless a rising edge of CK
A
or CK
B
occurs while that clock is enabled.
2. t
RSS
is the time needed to deassert RT
1
before returning to a normal FIFO cycle.
3. t
RSH
is the time needed before asserting RT
1
after a normal FIFO cycle.
4. Read and write operations to FIFO #1 should be disabled while RT
1
is being asserted.
