- Write a main program to flash a LED in a loop. Stop the flashing when a key is pressed and held. As soon as you release the key, flashing should continue. Don’t use interrupts. Dont wait in a loop for key press but once pressed wait in a loop for a key release. - In the main program flash a led. Write a delay subroutine using R6. Assume 2 switches are connected to P3.2 and P3.2. One key will increment the delay duration. The other will decrement the delay duration. Use interrupts. You need one more location to keep the duration so that the delay subroutine can copy it to R6.

Please solve according to 8051 microcontroller.
