A circle means that the switch is ON.

Note:

After the microprocessor sends serial data, TM1 to TM6 can be switched among the states listed

under ST1 to ST3 by input at the DC pin. First, if the microprocessor sends serial data when DC is

high, TM1 to TM6 are placed in the state listed under ST1. When DC is brought low, the states

change to the states listed under ST2. Then if DC is brought high again, the states change to the

states listed under ST3.
