Im using mc9s12p128 and im tryinng to count the pulses from PT7 until it reachhes a

value and calls an interrupt.


-Im using PT7 as PACLK (timer clock) and counting the signal

but im not sure where the compare is done or where i should

store the values for compairing.


-is it possible to use other timer channels to compare more than a

value with the timerCounter(while getting the timerClock from

PT7)? Example: Interrupt occurs when the value x is reached and y is reached.


-Does using PT7 as timer clock effects anything except timer?

(maybe ISR?)


Could you send an example code of initialisation for something like this.


Thank you.
