QUESTION (2)
For a microcontroller running on a 8 MHz clock assume that on
CCP1 pin (in/out pin attached to CCP module 1 that uses TMR1) a
signal with frequency fx,is applied. Assuming that the content of
TMRI is 100(10) at the beginning of the cycle, TMRI prescoler ratio
is 1, CCP1 pre scaler ratio is 4 and the content of TMR1 is
5200(10) after one cycle, determine the unknown input signal’s
frequency
1- fx = 691 Hz
2- fx = 823 Hz
3- fx = 939 Hz
4- fx = 1173 Hz
5- fx = 1396 Hz
6- fx = 1568 Hz
7- fx = 1994 Hz
8- fx = 2395 Hz
QUESTION(3)
For a microcontroller running on a 4 MHz clock assume that
CCP1 pin (in/out pin attached to CCP module 1 that uses TMR1) is
connected to TOCKI pin (external event input for TMRO). Considering
that our output is TMRO overflow eventldefine the parameters to be
programmed in so TMRO will generate an overflow every 100
seconds.
