Function
ZPUSH
(1) Saves the contents of the following index registers to after the device specified by
(When contents of an index register are saved,
• Basic model QCPU: Z0 to Z9
• High Performance model QCPU/Process CPU/Redundant CPU: Z0 to Z15
• Universal model QCPU/LCPU: Z0 to Z19
(2) The ZPOP instruction is used for data recovery. Nesting is possible within the ZPUSH to ZPOP cycle.
(3) If nesting has been done, each time the ZPUSH instruction is executed, the field used following
field large enough to accommodate the number of times the instruction will be used should be maintained from the
beginning.
(4) The composition of the field used following
• When Basic model QCPU is used
• When using a High Performance model QCPU/Process CPU/Redundant CPU
