The loopback function provides for at-speed testing of the transmit/receive portions of the circuitry. The enable function allows for all circuitry to be disabled so that an lddq test can be performed. The PRBS function also allows for a BIST( built-in self test). The terminal setting, TESTEN high, enables the test mode. The terminal TESTEN has an internal pulldown resistor, so it defaults to normal operation. The TESTEN is only used for factory testing, and is not intended for end-user control.
