5) The following figure shows the examples of 32-bit index setting using 'ZZ' and
their actual processing devices.
(With the setting of Z0 (32 bits) =100000 and Z2 (32 bits)=-20)

6) Functions that can use 'ZZ'
32-bit index settings using 'ZZ' can be used in the following functions.
ZZn cannot be used individually such as 'DMOV K100000 ZZ0'. When setting a
value to index registers to specify a 32-bit index setting using 'ZZ', set a value to
Zn (Z0 to Z19).
ZZn cannot be entered individually in the functions.
(c) 32-bit index setting for FXCPU
Combine index registers V (from V0) and Z (from Z0) for a 32-bit index setting.
V is used for high order and Z is used for low order. With the combination of the
specified Z and the corresponding V, the device can be used as a 32-bit register.
Note that the index setting is not applied by specifying the high order V.
Example: When specifying Z4, V4 and Z4 are used as a 32-bit register.
