(4) Index modification using extended data register (D) and extended link register (W)
(Universal model QCPU (excluding Q00UJCPU) and LCPU)
Like index modification using data register (D) and link register (W) of internal user device, a device can be specified by
index modification within the range of the extended data register (D) and extended link register (W).
1) Index modification where the device number crosses over the boundary between the internal user device and
the extended data register (D) or extended link register (W)
The specification of index modification where the device number crosses over the boundary between the
internal user device and the extended data register (D) or extended link register (W) cannot be made.
If doing so, an error occurs when the device range check is enabled at index modification (error code: 4101).
