Selects whether or not the data is refreshed when the COM instruction is
executed.
Designation of SD778 is made valid when SM775 turns ON.
Refresh between multiple CPUs by COM instruction is performed under
the following occasion.
Receiving operation from other device: b4 of SD778(refresh in the CPU
shared memory) is turned to 1.
Sending operation from host CPU : b15 of SD778(communication with
peripheral device is executed/nonexecuted) is turned to 0.

Selects whether or not the data is refreshed when the COM instruction is
executed.
Designation of SD778 is made valid when SM775 turns ON.
Refresh between multiple CPUs by COM instruction is performed under
the following occasion.
Receiving operation from other device: b4 of SD778(refresh in the CPU
shared memory) is turned to 1.
Sending operation from host CPU : b15 of SD778(communication with
peripheral device is executed/nonexecuted) is turned to 0.
When b2 (refresh of the CC-Link IE controller network and
MELSECNET/H) of SD778 is 1, the CC-Link IE controller network and
MELSECNET/H perform refresh.
Therefore, if there are many refresh points, processing time for the COM
instruction will be extended.
