Question

1. How many Timers does the F5529 have? Name them. What happens when the Timer overflows? And what exactly does "overflow" mean? 2. What is the name of the register that "counts?" 3. 4. What is the name of the Timer A Interrupt Flag? 5. What is "resolution?" State 2 ways you can change it. What are the different Timer Modes and how do they work? 6. 7. What is the advantage of Up Mode vs Continuous Mode? What settings would you need to generate an interrupt about every 16 seconds using ACLK in 8. Continuous Mode? (Hint: similar to #3 in Lab 6a). If I wanted to blink LED2 (green) every 2 seconds and LED1 (red) every 1 seconds, how would I 9. set it up using Timers and Interrupts? You need not write any code, just explain how you would do it. (Hint: I'm not looking for a long answer here, but you'd have to do something different than what you did in lab). 10. What is the advantage of using Timer Interrupts to blink the LED? Why not just do what we did in Lab 2?

Answer 1

2. When the timer overflows it rolls over and keeps counting more. Over flow means it has reached its limit value.

5. Resolution refers to the count of pixels displayed in a screen .

I) press f12 to get advanced menu options .

II) use up arrow to select an required options.

6. The timer modes are

I) mode 0

II) mode 1

III) mode 2

IV) mode 3

Timer 0 and 1 works as a 8 bit counter in mode 0 . Timer mode 1 is commonly used and it is 16 bit. Mode 2 counters are automatic reload. Mode 3 is known as split counter .
