57% 3:55 pm 1 minute ago and a CTC mode cj here the conrdsre compared with the OCR onty the Semer is cleared d mone of the mentioned negister, if valus resource provides clock puise to AVR timers if CS02-0 a) internal clock of the AVR b) external clock of the AVR c) none of the mentioned d) all of the mentioned 10. TIMSK register is used for aj knowing the status of the timer count b) masking the interrupts flags of the Timero, Timert and Tinm c) resetting the value of the interrupts 11. Which register is responsible for handling all the external ha a) TIMSK b) GICR c) MCUCR 12. By default, INTO-INT2 interrupts are: a) edge triggered b) level triggered c) all of the mentioned d) none of the mentioned

Explanation / Answer

8).c). In CTC(Clear time on Compare) mode, The content are compared with the OCR Register. And if the value matches then the timer get cleared.

In CTC mode has one compare register, where we can set value to compare with the Timer / counter register value. Once the compare value matches with timer register value, compare match occurs. This compare match event can be used for waveform generation.

9).b). External clock of the AVR is used if CS02-00=6..

10).b). Masking the interupt flag of timer 0, timer 1, timer 1A.

11).
