In this unit, the terminal with asterisk mark (*) is (open) terminal which is not connected to the outside.
Note 1: "fsi" means the word clock (LRCI) on the input side, and "fso" means the work clock (LRCO) on the output side.
Note 2: When H level is set, "open" is also applicable.
Note 3: When the terminal of plural terminal Nos. For the same terminal name is used, it does not matter whether either or both
terminals are connected.
