Data Type: Sixteen bit word.
USAGE: Data in these registers come from the system self test or the SROM CRC test. The data can be read out 0x0d,
or 0x0d first, then 0x0c.
System test results:
SROM CRC Test Result:
Data_Out_Upper
0x1B
0xBE
Data_Out_Lower
0xBF
0xEF
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.
