In the program example created with the RRPA instruction (auto refresh parameter
setting) on the ACPU/QCPU (A mode), RWr0 - RWr7 are assigned to D456 to D463.
POINT
Depending on the CPU module, the devices used in the program examples of this
chapter may be unusable. For the valid ranges of the devices, refer to the users'
manual of the CPU module.
For example, when the A1SCPU is used, devices of X100, Y100 and later cannot
be used. Use the devices such as B and M.
