 **mcrfm** - Move CR Field, masked.
 
+This instruction copies, sets, or inverts parts of a CR Field
+into another CR Field.  `mcrf` copies only one bit of the CR
+from any arbitrary bit to any other arbitrary bit, whereas
+`mcrfm` copies an entire 4-bit CR Field (or masked parts thereof).
+Unlike `mcrf` the bits of the CR Field may not change position:
+the EQ bit from the source may only go into the EQ bit of the
+destination (optionally inverted, set, or cleared).
