Hi !!

I'm trying to generate a PWM interrupt on match MR0 with this code:

PCB_PINSEL0 |= 0x00028000;      
GPIO0_IODIR = 0x00008000;               
GPIO0_IOSET = 0x00008000;           

VICVectAddr8 = (unsigned)IRQ_Routine;   
VICVectCntl8 = 0x00000028;                
VICIntEnable = 0x00000100;                

PCB_PINSEL0 |= 0x00028008;       
PWM_PR    = 0x00000000;                

PWM_PCR = 0x00000C0C;        
PWM_MCR = 0x00000003;                 
PWM_MR0 = 0x400;                         
PWM_MR1 = 0;                            
PWM_MR2 = 0x200;                       
PWM_MR3 = 0x400;                           
PWM_LER = 0xF;                           
PWM_TCR = 0x00000002;                    
PWM_TCR = 0x00000009;              

void  __attribute__ ((interrupt("IRQ"))) IRQ_Routine()
{
    static BOOLEAN bFlag=FALSE;
    if (!bFlag)
    {
        bFlag=FALSE;
        GPIO0_IOCLR=0x00008000;
    }
    else
    {
         bFlag=TRUE;
         GPIO0_IOSET=0x00008000;
    }

    PWM_IR       |= 0x00000001;               
    VICVectAddr  = 0x00000000;
}


The PWM is generate correctly but the interrupt not,have you got any
idea, the code is from Keil I think. Have you got any idea?

Thanks
