17.1 FNC102 – ZPUSH/Batch Store of Index Register
17.1 FNC102 – ZPUSH/Batch Store of Index Register
Outline
This instruction temporarily batch-stores the present value of the index registers V0 to V7 and Z0 to Z7.
For restoring the present value of temporarily batch-stored index registers, use ZPOP (FNC103) instruction.
→ For ZPOP (FNC103) instruction, refer to Section 17.2.

Explanation of function and operation
1. 16-bit operation (ZPUSH/ZPUSHP)
1) The contents of the index registers V0 to V7 and Z0 to Z7 are batch-stored temporarily to and later.
When the contents of index registers are batch-stored, the number of times of batch-storage is
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 , ZPUSH (FNC102) and ZPOP (FNC103) instructions can be used
in the nest structure.
In this case, the occupied points are added by "16" after every time ZPUSH (FNC102) instruction is
executed. Secure in advance sufficient area for the number of the next structure.
