2lg high low high low 1000 2000 2500 3000 4000 INTO (clock cycles) Note that the unit of time is the clock cycle. The goal is to measure the time (in clock cycles) of the high period and the low period and save them to high and low variables. Use Timer 1 and its register TMR1 to measure the time. To simulate the signal to INT0, use Stimulus (Pin/Register Actions) (20 pt) Write a C program using polling and run the simulation. Report the value of high and low variablesie. 4 numbers) a. (20 pt) Write a C program using an interrupt and run the simulation. Report the value of high and low variables (i.e. 4 numbers) b. (20 pt) Are these high and low variables close to 1000, 500, 500, 1000? Briefly discuss why the results you obtained are not exactly the same to the ideal values c. 2lg high low high low 1000 2000 2500 3000 4000 INTO (clock cycles) Note that the unit of time is the clock cycle.
