CENTERALIGNED pwm not working

[gm.1]

iam using stm8s003f3 microcontroller i configured centeraligned pwm but not working

attached wave form also please suggest.

void TIM1_setup(void)

{

   TIM1_DeInit();

   TIM1_TimeBaseInit(0, TIM1_COUNTERMODE_CENTERALIGNED3 , 1000, 0);

   TIM1_BDTRConfig(TIM1_OSSISTATE_DISABLE,TIM1_LOCKLEVEL_OFF, 10,TIM1_BREAK_DISABLE,TIM1_BREAKPOLARITY_LOW,TIM1_AUTOMATICOUTPUT_DISABLE);

   TIM1_OC1Init(TIM1_OCMODE_PWM2, 

         TIM1_OUTPUTSTATE_ENABLE, 

         TIM1_OUTPUTNSTATE_ENABLE, 

         1000, 

         TIM1_OCPOLARITY_LOW, 

         TIM1_OCNPOLARITY_LOW, 

         TIM1_OCIDLESTATE_RESET, 

         TIM1_OCNIDLESTATE_RESET);

   TIM1_OC2Init(TIM1_OCMODE_PWM2, 

         TIM1_OUTPUTSTATE_ENABLE, 

         TIM1_OUTPUTNSTATE_ENABLE, 

         1000, 

         TIM1_OCPOLARITY_LOW, 

         TIM1_OCNPOLARITY_LOW, 

         TIM1_OCIDLESTATE_RESET, 

         TIM1_OCNIDLESTATE_RESET);

  TIM1_CtrlPWMOutputs(ENABLE);

  TIM1_Cmd(ENABLE);
