Thank you. Could you please give me some additional detail on what to check Is it right to assume that if the reset pin is high (no reset) some data transfer activity should be recorded Which one is the chip enable pin The halt pin eventually I could not figure it out on the datasheet :(
I need some guide on this, never ever had to fight with a cpu...
Also, in the schematics i see only the connection to U15 (ls245), is that chip the one i should focus on
(Thanks for the help everyone)
