This paper concentrates on the primary theme of verify that your interrupt is working correctly, designate a port pin as an output, and toggle it every time the timer ISR is run in which you have to explain and evaluate its intricate aspects in detail.

For the time base, you are to set up a timer that interrupts the processor every 10 mS. In order to verify that your interrupt is working correctly, designate a port pin as an output, and toggle it every time the timer ISR is run. Connect the pin to the oscilloscope so that you can verify it is exactly 10 mS on, and 10 mS off.
To save CPU cycles, switch inputs should be set up to only be read on a change of value. This can be done by using the interrupt-on-change feature of RB4-RB7. You are free to select any valid port pins to drive the LED, and output the square wave produced by the timer ISR.
