FB-DIMM Reset Timing
SPCPC[1:0] - Spare Copy Control
These controls set up sparing for each branch. Branch zero (device 21) takes
precedence over branch one (device 22): if both spare-control-enabled branches’ spare
error thresholds trigger in the same cycle, sparing will only commence on branch zero.
Sparing will not commence on a competing branch until its in-progress competitor’s
spare control enable is cleared and it’s UERRCNT/CERRCNT criteria is still met.
