Hi,
I'm trying to read the status of PA5 pin. I configured the PADR & PAOR to input-pullup, but i can't get the pin's status on the PADR.. when i do the same thing with PA7 - it works ok... Does any one know why?! thanks Itamar p.s. I work with the inDart evaluation board2003-11-09 06:17 PM
Be aware that there is a series resistor between your application and the ISP ports. This may change your signal levels. PA5 is an ISP input and therefore does have a 4k7 resistor in series. Check 'InDart User's Manual' page 6.

Thanks, but i had the same problem with PA2/1 too..
any more ideas? itamar2003-11-11 05:42 PM
Hi,
In case of debugging with inDART, the ICCCLK and ICCDATA lines are used for communication between the PC and device. For Lite29 these are on port A. I am guessing that when you are manipulating port A you are changing PA6 and PA5 by mistake.(You should not touch even the corresponding PADDR/PAOR bits for these two lines) This could be corrupting data and causing the problem. Hope this helps...
