Hello.
I have 12F1840 which is connected to MAX7219. As amount of ports is quite low, 3 ports are wasted on driving that IC. I would like to be able to use any of these pins for reading a button or driving a buzzer. If I understand properly, if I drive MAX7219 CLK pin low, IC will be locked, no matter what happens on other pins, right?
