ST10 interupt handling problem

Hi,

I'm using Timer T6 to generate a clock for a device and I want to keep a count of these clock pulses.

Also I want to use CC12 as positive edge interupt (P2.12). I have kept the priority of this interupt higher than that of the timer.

I have pasted the code to achieve this below.

My problem is that when I try to give interupt on P2.12, the CPU enters T6 interupt routine.

Please can anyone help me solve this problem.

Thanks and regards
Sonali
