(b) Device data fetch
When the data of a device that has been set indirectly is switched from the
REAL to VIRTUAL mode, first acquire everything as default values and
thereafter carry out fetch control during virtual mode operation for the
corresponding module.
Shown in the table below are the fetch timing of each device and the refresh
cycle of the set device.
