If flow control is disabled, this setting affects the FIFO buffer size directly.
If flow control is enabled, this setting affects the size of the threshold.
FIFO Buffer Size
The sizes of the FIFO buffers, when flow control is enabled, along with the
calculations of those sizes are displayed in the Parameterize - SerialLite
MegaCore function wizard
shows the case where optimization against starvation has not been
selected. In this example, the maximum packet size determines the
priority data receive FIFO buffer size.

been selected. In this case, the priority data receive FIFO buffer size is
dominated by the starvation setting, creating a large enough FIFO buffer
that the packet size has no impact.
Figure 3–30. FIFO Buffer Sizing (Flow Control Without Starvation Option)
Ensures that the FIFO buffer (if flow control is disabled) or the FIFO buffer
threshold (if flow control is enabled) is large enough to hold the specified
number of packets. Available only if the priority data port is enabled.
