1) The contents of the index registers V0 to V7 and Z0 to Z7 which were batch-stored temporarily to 
 and later
are restored to the original index registers.  When the contents of the index registers are restored, the number of
times of batch-storage 
 is decremented by "1".
2) For temporarily batch-storing the data, use ZPUSH (FNC102) instruction.
Use ZPUSH (FNC102) and ZPOP (FNC103) instruction as a pair.
