ARM OMAP 3530 FIQ timer interrupt .

Hi,
I am facing problem with the TCRR register while generating FIQ timer interrupt using GPT10 .
It is generating interrupt for 1 hr and stops when the TCRR register value read as 0x80793241 or reaches 0x80XXXXXX.
I have read the ref manual but unable to get any idea to remove this issue so that it can generate the interrupt continuously.
Please help me in solving this issue.

Thanks .
Vivek
