6.4 Extension No.
The Extension No. is that specified by the remote output [RYn0 to RYn5 or RYn6 to RYnB] to select
data processed by the remote register.
If the necessary data is selected from the following table and its Extension No. is specified by the
remote output [RYn0 to RYn5 or RYn6 to RYnB], it can be processed by the remote register.
