ENABLE
This bit is set to 1 if the FIFO needs to be configured as a packet FIFO. By default, the FIFOs
are configured as ATM cell FIFOs.
Writing a 0 to this bit disables a FIFO. If previously enabled, a disabled FIFO does not
accept any new data but does continue to assert Data Available internally until it is drained
completely. During operation, FIFOs must be disabled before being reconfigured.
