Hello!


1) I found that AT89C51RE2 support оn-chip Debug via 2 wires;

Please advice the schematic, program and if exist any How-To resource.


2) Besides, keil.com on their website asserts that Labcenter Electronics Proteus VSM supports ,AT89C51RE2,. Im using last v7.8 SP2 and there are no any similar chip like RE2. May be they mean 3-rd party simulate model ? Need to simulate 2 MCU.

Thanks a lot.
