SDSTH[11:0]:
The SDSTH[11:0] value represents the allowable number of B2 errors that
can be accumulated during an evaluation window before an SD threshold
event is declared. Setting this threshold to 0xFFF disables the saturation
functionality. Refer to the Operations section for the recommended settings.
