PWM USING QOM function

Hi I am trying to attain PWM waveforem using QOM function ,the problem i face is that o/p remains at low continously...here is my code can someone plz help me out.I am using channel 0 and tcr1 as timebase
 

 TPUMCR_A     =0x6020;
 TICR_A       =0x0000; 
 CIER_A       =0x0001;
 CFSR0_A      =0x0000; 
 CFSR1_A      =0x0000; 
 CFSR2_A      =0x0000; 
 CFSR3_A      =0x000E; 
 CPRO_A       =0x0000; 
 CPR1_A    =0x0000; 
 CISR_A       =0x0000; 
 TPUMCR2_A    =0x0000;
 TPUMCR3_A    =0x0000; 
 CHANNEL0_0_A =0x00F7;
 CHANNEL0_1_A =0x0000;
 CHANNEL0_2_A =0x03AB;
 CHANNEL0_3_A =0x1674;
 HSQR0_A      =0x0000;
 HSQR1_A      =0x0002;
 HSSR0_A      =0x0000;
 HSSR1_A      =0x0002;
 CPR1_A       =0x0003;
