NOTES:
1. Mailbox feature is not supported in depth expansion applications. (MBA + MBB tie to GND)
2. Transfer clock should be set either to the Write Port Clock (CLKA) or the Read Port Clock (CLKB), whichever is faster.
3. The amount of time it takes for EF/OR of the last FIFO in the chain to go HIGH (i.e. valid data to appear on the last FIFO’s outputs) after a word has been written to the first FIFO is the
4. The amount of time it takes for FF/IR of the first FIFO in the chain to go HIGH after a word has been read from the last FIFO is the sum of the delays for each individual FIFO:

sum of the delays for each individual FIFO: (N - 1)*(4*transfer clock) + 3*T
