-* lbzupsx RT,RA,RB
+* lbzupsx RT,RA,RB,SH
 
 Pseudo-code:
 
-    EA <- (RA)
+    EA <- (RA)<<(SH+1)
     RT <- ([0] * (XLEN-8)) || MEM(EA, 1)
     RA <- (RA) + (RB)
 
 Description:
 
-    Let the effective address (EA) be register RA.
+    Let the effective address (EA) be the sum of the contents of
+    register RB shifted by (SH+1), and the contents of register RA.
 
     The byte in storage addressed by EA is loaded into RT[56:63]. 
     RT[0:55] are set to 0.
