40051 Write Control
Values to BST The BAS must write a 1 to this location for the first 4 values to
be copied across the SSD device, to the BST side. In normal
operation update the 4 registers 40200 through 40203 fairly
regularly. Once all four have been written, write a one to
40051. This is done to insure that all control values are copied
to the BST side of the SSD as a block.

parameters to the BAS side of the SSD. The BAS should
never read or write this address.
