System Test: This test is initiated via the Configuration_Bits register. It performs several tests to verify that the hardware

is functioning correctly. Perform a hardware reset just prior to running the test. SROM contents and register settings

will be lost.

SROM CRC Test: Performs a CRC on the SROM contents. The test is initiated by writing a particular value to the

SROM_Enable register.
