CC2430 Timer 3

Hello,

I am using CC2430 TI Chip with Keil compiler.
I am having problem in setting up Timer 3 settings. Going through CC2430.pdf document.
I have below TIMER 3 settings I tried running the code under simulation mode on KEIL compiler.
the program is not breaking for interrupt as counter value is not being incremented. Can anyone look at the settings and let me know where I am going wrong as coounter is not incrementing.

TIMER 3 SETUP :

T3IF = 0
T3IE = 1
T3CTL = 0XFA
T3CC0 = 0XFA
T3CNT = 0X00
T3CCTL0 = 0X4C
T3OVFIF = 0
T3CH0IF = 0
EA = 1

any help would be appreciated....
Thanks in advance...
