#99531 - Well. . . Responding to: ???'s previous message |
A cursory glance at the code shows that the RAMtest routine is written to the ram chip and then executed there, causing the green light to come on. Not quite sure yet why the red led would come on. Possibly something to do with the LJMP from address 800x not really going to where RAMtest: actually resides in code memory? |
