External Interrupt using RCM5400W

Hi, I'm having problems with external interrupt using a RCM5400W by PE0,

May somebody show me any sample code of external interrupt PE0 or PE1.

I need a sample about external interrupt configuration and interrupt service routine, thanks for help me.

Try this.

#class auto

unsigned int count0, count1;

void my_isr0();
void my_isr1();

void main()
{
count0 = 0;
count1 = 0;

WrPortI(PEDDR, &PEDDRShadow, 0x00); // set port E as all inputs

SetVectExtern3000(0, my_isr0);
SetVectExtern3000(1, my_isr1);
// re-setup ISR's to show example of retrieving ISR address using GetVectExtern3000
SetVectExtern3000(0, GetVectExtern3000(0));
SetVectExtern3000(1, GetVectExtern3000(1));

//WrPortI(I0CR,&I0CRShadow,0x07);
WrPortI(I0CR,&I0CRShadow,0x05);
//WrPortI(I0CR,&I0CRShadow,0x0B); // External Interrupts
WrPortI(I1CR, &I1CRShadow, 0x09); // enable external INT1 on PE1, rising edge, priority 1
while ( count0 < 2000) {

// output the interrupt count every second
costate {
printf("counts = %3d %3d\n", count0, count1);
waitfor(DelaySec(1));
}
}

// final counts
printf("counts = %3d %3d\n", count0, count1);
}
/****** interrupt routines ******/

nodebug root interrupt void my_isr0()
{
count0++;
}
nodebug root interrupt void my_isr1()
{
count1++;
}

You should be careful to only modify the bits of PEDDR for the pins you're trying to set up. Other peripherals on the chip may be using pins from Port E as outputs, and the WrPortI() will screw things up!
