4-3-9 DIP Switch Circuit 
 
The key Board Circuit consist of the scan signal of 4 lines and the return signal of 4-line. The CPU sends 
repeatedly and continuously the scan data R1, 2, 3, 5 through P10.0~10.2, P1.1. The DIP S/W information 
input in the return signal if the specific DIP S/W is ON Status during the given time. The CPU reads the data 
through C1~C4 and analyzes what DIP S/W is ON and performs the selected function.
