micro-controller PIC18

The PIC trainer board is programmed as follows: . The interrupt priority system is enabled. Timer 2 is configured to generate a low-priority interrupt every 10 ms; its handler increments variables representing minutes, seconds, and hundredths of a second for a real- . The PB1 pushbutton (connected to the INT1 pin) is configured to generate a high-priority . The main program loop fetches the values of the clock variables and displays them on the 1. Draw a diagram illustrating the sequence of instructions executed when a timer interrupt 2. What sequence of instructions is executed if a pushbutton interrupt occurs while the processor time clock. interrupt when pressed; its handler resets the clock variables to zero. LCD occurs. Repeat for a pushbutton interrupt. is servicing a timer interrupt? What about a timer interrupt while the processor is servicing a pushbutton interrupt?
