remains HIGH for the duration of the button press and then goes LOW
•
Each button press latches the states of D1, D2 and D3
•
D1 toggles state from Button 1 press to Button 2 press
•
D3 is always HIGH if DIP switch 10 is in the OFF position
•
D3 is always LOW if DIP switch 10 is in the ON position
•
D2 toggles state between button 1 press and button 2 press when DIP switches 1 and 3 are not
both set to ON or OFF
