The ADV7842/ADV7844 contains a BIST (Built in Self-Test) for the external memory. This test can be used to test the operation of the external memory interface. It checks the connections between the ADV7842/ADV7844 and the external DDR memory. The test is controlled through I2C and the test results can be read back through registers within the ADV7842/ADV7844.
