    CCU8 PWM synchronous : Start, Stop and Restart

    Hi All,

    I have successfully started CCU8 PWM for slice_0 and slice_2 in synchronous mode.

    After initializing CCU8 global and slice registers. I am using the following command to start the PWM synchronously.

    Code:
    XMC_SCU_SetCcuTriggerHigh(XMC_SCU_CCU_TRIGGER_CCU80);
    I am stopping the PWM with following code :

    Code:
    	CCU80_CC80->TCCLR = ((uint32_t)CCU8_CC8_TCCLR_TRBC_Msk);
    	CCU80_CC80->TCCLR = ((uint32_t)CCU8_CC8_TCCLR_TCC_Msk);
    	CCU80->GIDLS      = 1 << 0;
    
    	CCU80_CC82->TCCLR = ((uint32_t)CCU8_CC8_TCCLR_TRBC_Msk);
    	CCU80_CC82->TCCLR = ((uint32_t)CCU8_CC8_TCCLR_TCC_Msk);
    	CCU80->GIDLS      = 1 << 2;
    The problem I am facing is :
    • After stoping PWM, depending on condition, I have to again restart the PWM in synchronous mode but its not starting.
    • I have even tried to call the previous CCU8 initialization routine and using XMC_SCU_SetCcuTriggerHigh(XMC_SCU_CCU_TRIGGER_CCU8 0); tried to restart the PWM, but it is not at all restarting

    I need help to restart the PWM in synchronous mode after stop condition.

    Guide me in this regard.

    Thanks.

    Tinchu
