hi @ all!
I'm definitive not a newbie in this avr stuff, but I have problem and no explanation!
May be my mind is messed up in the meantime!
I enabled all pull ups on an attiny13 connected to my pc via jtag ice mk-II debugwire! I've LED's connected to the IO's and I can see, that I have really a pull up effect: the led's are smoldering!
But, when I read out PIN registers I can not see any "high - info"! Everything is zero!
