Err, another stupid question,
When the microcontroller chip is connected by 5V DC power supply to input high voltage(Logic 0) for active low input pin, so that when the switch is pressed, a low voltage is input(Logic 1) into the pin, why do we need to connect a capacitor in parallel to the input connections?
(See the figure in the attached documents.)
Another question:
What is the exact function of the MCLR.L pin in the microcontroller as shown in the figure? Does it reset all the programming, or only resetting the outputs to give logic zero at the instant of resetting?
