Hello :

I want to use ccp2 in capture mode, but I dont understand why CCP2IF is
always '0'.

I do this init:

 TMR3H =   0x00;
 TMR3L =   0x00;
 T3CONbits.TMR3CS =  0;
 T3CONbits.TMR3ON =  1;

 CCP2CON =   0x00;
 TRISBbits.TRISB3=  1;
 CCP2CON =   0x04;
 PIR2bits.CCP2IF =  0;
 PIE2bits.CCP2IE =  1;
 INTCONbits.PEIE =  1;
 INTCONbits.GIE  =  1;
 message = 0;

And then, in my interrupt routine I do this:

void InterruptHandler()
{

 if(PIR2bits.CCP2IF && PIE2bits.CCP2IE)


        PIR2bits.CCP2IF = 0;
        message = 1;
 }
 return;
}

Value of 'message' is always 0 because CCP2IF is always 0, and I am sure
that in my RB3/CCP2 pin I have a signal changing between 5v and 0v every
second.

What is happening?
