Explanation of function and operation
1. 16-bit operation (ZPOP/ZPOPP)
→
For the function and operation, refer also to Section 17.1.
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.

Errors
An operation error is caused in the following cases; The error flag M8067 turns ON, and the error code is
stored in D8067.
• When the number of times of batch-storage (D) stores "0" or a negative value while ZPOP (FNC103)
instruction is executed (error code: K6706)
