there is a strange behavior:

a porta pin configurated as logic input changes to output and toggles each 50 to 500ns.

i do not write to the csiop-register via my progcode.

is there any errata sheet for the 3233B ?

thanks in advance !!

Port A works fine.

Go back to your PSDsoft project and check your selections for the Port A pin in question. I suspect you have selected a pin function that you don't desire.

port a4 is cpld input in psd express:

logic or address

but changes to output sometimes ?!

what if i define it as input in psd express and overwrite this

settings with my soft changing the port a direction via csiop+02

or csiop+06 ????

will i overwrite the psd express settings?

thanks again !!!!!
