intraffic
---------
This example shows how the EZ-USB input FIFO interface is used.
A traffic generator sends test data to the EZ-USB. The hosts PC reads
out this data and verifies it.
The traffic generator is implemented in the FPGA and supports two modes:
1. (IOA3=0) This mode supports data flow control using FIFO full flag
(FLAGB) and SLWR control pin. Use this mode as starting point for
data acquisition applications.
2. (IOA=3) In this mode and uninterrupted test pattern is generated,
i.e. flow control is disabled. This mode is used for performance
measurements (speed rate and interrupt measurements)
