Remarks:
1. When n = K1, D
2
will occupy one register. When n = K2, D
2
will occupy 2 consecutive registers.
2. Follow the methods below for the transistor scan output:
a) When X10 = On, DSW instruction will be executed. When X10 goes Off, M10 will keep being On until the
scan output completes a scan cycle and go Off.
b) When X10 is used as a button switch, whenever X10 is pressed once, M10 will be reset to Off when the scan
output designated by DSW instruction completes a scan cycle. The DIP switch data will be read completely
and the scan output will only operate during the time when the button switch is pressed. Therefore, even the
scan output is a transistor type, the life span of the transistor can be extended because it does not operate
too frequently.
