Timer enabling inside timer interrupt

[variaseng]

Hi, I want to ask if it is alright to enable a timer inside an interrupt of a timer. Basically, I want to have a conditional function inside a timer interrupt routine and I want to see if the time passed when this conditional function was accessed is greater than a certain time, for example 1 usec. For example,

1. Code enters timer1 interrupt routine.
2. Inside the routine, timer2 is enabled. I want timer2 to count until a certain PR and I want this timer2 to continue counting even after the routine is over.
3. Code exits timer1 interrupt routine.
....Timer2 continues to count.
4. Code exits timer1 interrupt routine again.
5. I check PR to see if the count (corresponding to the time passed) is greater than the PR for 1usec.

Thank you very much for your help!
