S08MP16 Fault Interrupt not working

abicash — Sat, 09 Nov 2013 05:22:31 GMT

Hello

Somehow it isn't working now on a final board.Earlier on a perf board it worked every time the pin was fed with a 5v signal.

Now no interrupt is asserted.

Can the pin have become faulty? i have pulled the pin low with external resistor to avoid spurious glitches.

Here is my part of fault init code

{

FTM2MODE = 0xC5;

FTM2FLTCTRL = 0x11; //Fault 0 and Filter 0 enabled
FTM2FAULTFILTER_FFVAL = 0x0F; // FFVAL x system clock = 0.9us

}

heres the ISR

void interrupt 4 FTM2FAULT_ISR (void)

{

FTM2OUTMASK = 0x3F; //stop channels

FTM2FMS_FAULTF = 0;

}

what is wrong? can someone point out?

It seems the pin is non functional.

It works on another board.

FYI

Thanks and regards
