NOTES:
1. tRSS and tRSH need not be met unless a rising edge of CKA or CKB occurs while that clock is enabled.
2. tRSS is the time needed to deassert RT2 before returning to a normal FIFO cycle.
3. tRSH is the time needed before asserting RT2 after a normal FIFO cycle.
4. Read and write operations to FIFO #2 should be disabled while RT2 is being asserted.
