(Note-1): The state of a device is not in agreement when the device of a remark column is turned ON/OFF directly. In addition,
when the request from a data register and the request from the above device are performed simultaneously, the
request from the above device becomes effective.
(Note-2): It can also be ordered the device of a remark column.
(Note-3): It is unusable in the SV22 advanced synchronous control.
(Note-4): Do not use it as a user device. It can be used as a device that performs automatic refresh because of area for the
