Command
input
1) The contents of the index registers V0 to V7 and Z0 to Z7 are batch-stored temporarily to
When the contents of index registers are batch-stored, the number of times of batch-storage
incremented by "1".
2) For restoring the batch-stored data, use ZPOP (FNC103) instruction.
Use ZPUSH (FNC102) and ZPOP (FNC103) instruction as a pair.
3) By specifying a same device to
in the nest structure.
In this case, the occupied points are added by "16" after
executed. Secure in advance sufficient area for the number of the next structure.
