Action sequence of eight-character flexible line selection circuit

1. Calculate the first set of linear signals l 1 and l2, and then calculate the second set of curve signals c 1 and c2.

2. Secondly, according to the flexible requirements of the eight-character signal, operate each branch selection circuit in turn.

3. Finally, after the operation of all switch circuits is completed, conduct a comprehensive confirmation to ensure the correct state of each signal and switch.
