9S08PL4 PTA4, PTA5 USED AS OUTPUT

Hi All,

I am new to this particular device and have a strange problem with it. All 6 PTA pins are used as outputs, the load is minimal, driving CMOS inputs.

My program starts and does what it should, on the other port pins, but these two turn HI and no matter what I do, they stay there.

I already won the battle with the WATCHDOG. Is there anything else overwriting these two out of POR?

Thanks for a possible quick answer

Laszlo

I got it running, "case closed". BKGD and RESET activated out of POR; had to disable. FUN...
