Hi, i´m working in a project that needs a highspeed microcontroller so i´m using the dallas DS89c420 microcontroller; the problem is i can´t make it work. I´m using keil to compile, and an EETOOLS chipmax programer; i´t seems to program the micro OK but no program runs properly even a simple one like ....cpl p1.0....etc can anyone help me please, it´s very important, i know the program is ok because i´ve tested it with the at89c52 but this micro is just to slow for my needs.
Perhaps is the ds89c420 basic circuit diferent than the at89c52 basic circuit? Or is it a problem with noise or something like that??
