Usage of Split/Lock Configuration

When the two cores are "locked", it gives you dual redundancy.  Basically, you do the same operation on both cores and check that they got the same result.  The idea being that if you had something like a radiation strike, even if it affects both cores, it result in different errors on each core.  Therefore you could detect that the error occurred.  So it is useful where correct operation is vital and/or where the higher chance of things such as radiation strikes.

With "split" you get two cores, which are each running independently.
