Problem with TPU QOM function (urgent plz respond )

Hi,
     I have been trying to generate a PWM waveform using TPU QOM 
function my code is as follows
 TPUMCR_A      =0x60A0;
 TICR_A        =0x0700; 
 CIER_A        =0x8000;
 CFSR1_A       =0x0000; 
 CFSR2_A       =0x0000; 
 CFSR3_A       =0x0000; 
 CPR1_A        =0x0000;
 CISR_A        =0x0000; 
 TPUMCR2_A     =0x0000;
 TPUMCR3_A     =0x0000; 
 CFSR0_A       =0xE000;
 CHANNEL15_0_A =0x00F7;
 CHANNEL15_1_A =0x0000;
 CHANNEL15_2_A =0x01D7;
 CHANNEL15_3_A =0x01D6;
 HSQR0_A       =0x8000;
 HSQR1_A       =0x0000;
 HSSR0_A       =0x8000;
 HSSR1_A       =0x0000;
 CPR0_A        =0xC000;

Can anyone suggest me what went wrong in this i need this very 
urgently,

regards,
Sasanka.G.V
