Timer RJ unit


I am using R5F10BGG microcontroller, I want to run the Timer RJ unit at lower frequency of 15K HZ. I configured the register which is generated through the Applilet by selecting the mode-->count mode, frequency FIL at 1ms. Now if I integrate with my project, I am not getting interrupt which is suppose to give interrupt after TRJ0 register under flows  . If I run the timer RJ at FCKL (main On Chip Clock) clock it is generating the interrupt at 1ms. So what would be the reason for this (which is not giving interrupt at FIL) please suggest.
