Onboard Memory BIST
ScanMaster memory BIST enable. This bit is self clearing when BIST result is written
to the Memory BIST Result bit in the Status register.

Note 12:
Write capability to the register is only for test and debug purposes. Drivers should disable writes to register during normal operation.
Note 13:
Results of Compare bit is toggled after a compare is complete and it is set to the mismatch state when sequencer is kicked off again. Remains in last state
until next compare completed or until set to the mismatch.
Note 14:
Reserved Using Vector x for future growth for the number of vectors.
Note 15:
Half full or half empty designates 56 long words.
