Two errors (text) > 1 error (diagram). ^-^ Anyway, both are wrong. -----Original Message----- From: Matthew Miller [mailto:namiller2@naxs.net] Sent: Friday, June 24, 2005 8:00 AM Mark, I don't think you're crazy. Whoever wrote this portion of the datasheet made a few mistakes. The PC can address from 0000h-01FFF, but only 01000h of the locations are implimented. While both diagram and text are wrong, I think the diagram is more correct. ;^) Matthew. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
