• The designated device number for
data processed by the instruction
exceeds the usable range.
• Alternatively, the stored data or
constants for the devices designated
by the instruction exceeds the usable
range.
• In the settings of write to the host
CPU shared memory, the write
designation disabled area is
specified as the write destination
address.
