A. some externally applied frequency f’
B. controller’s crystal frequency f
C. controller’s crystal frequency /12
D. externally applied frequency/12
Answer:A
What is the frequency of the clock that is being used as the clock source for the timer?
A. some externally applied frequency f’ B. controller’s crystal frequency f C. controller’s crystal frequency /12 D. externally applied frequency/12
Explanation: The frequency of the clock source for the timer is equal to f/12( where f is frequency of the crystal ).
