4) Usage range of index registers
The following table lists the usage range of index registers when setting
indexes in 32-bit range.
Since the specified index register (Zn) and next index register (Zn+1) are used
for index setting in 32-bit range, make sure not to overlap index registers being
used.
5) The following figure shows the examples of index setting and their actual
processing devices.
(With the setting of Z0 (32 bits) =100000 and Z2 (32 bits)=-20)
