Selecting the backup option results in a larger receive FIFO buffer and
slightly more logic being used.
Selecting the Trigger Port
Either or both of the data ports can be used to trigger flow control (see
Table
flow control. Flow control increases the sizes of receive FIFO buffers. If
both data ports are implemented, then memory usage can be reduced if
your design requires only one of the ports to trigger flow control.

A second FIFO buffer threshold is established, and logic is
created to send a second
if flow control is enabled.
No second FIFO buffer threshold is established. Available
only if flow control is enabled. This is the default setting.
Trigger flow control when the regular data port receive FIFO
buffer breaches a threshold. Available only if flow control is
enabled and the regular data port is enabled. If the priority
data port is not enabled, then this is the only option allowed.
Trigger flow control when the priority data port receive FIFO
buffer breaches a threshold. Available only if flow control is
enabled and the priority data port is enabled. If the regular
data port is not enabled, then this is the only option allowed.
Trigger flow control when either the regular data port
receive FIFO buffer or the priority data port receive FIFO
buffer breaches a threshold. Available only if flow control is
enabled and both data ports are enabled. This is the default
setting if both data ports are enabled.
