[avr-chat] M8535 ports

Hi,
I just noticed this on a m8535 project I'm debugging.. I have a PORTC pin as o/p, programmed high. But when I switch a neighbouring port line, the other drops from 5V to 3.7V, also it seeems to be slowly oscillating from 3.7V to 5v. I tried external pullups etc. but to no effect. Does any one have a clue?

Thanks,
--Royce.
