+## Load/Store-Multi (selective)
+
+Up to 64 FPRs will be loaded, here.  `r3` is set one per bit
+for each FP register required to be loaded.  The block of memory
+from which the registers are loaded is contiguous (no gaps):
+any FP register which has a corresponding zero bit in `r3`
+is *unaltered*.  In essence this is a selective LD-multi with
+"Scatter" capability.
