Reset 89C51Rx2H

[Saurabh Mukadam]

I am writing my own downloading program for 89C51RD2Hxx series. I am able to put 89C51RD2Hxx series in programming mode. Able to load the new application program in the code.

I want to reset the 89C51RD2Hxx so that new application can be executed. To reset what is the command ? Is there any source code available ? Is there any reset command which can be send to 89C51RD2Hxx during a program mode ?

kick the puppy and do not feed it.  Sorry, start the watchdog and let it time out, that will reset your controller.

already in programming mode..How do i start watchdog

RD2H rev G and later with FlashMagic will use the watchdog to restart.

Hi Erik,

I am writing my own Downloading application. What is the command to start the watchdog inside in the RD2H rev G. What does Flash Magic sends the command to RD2 to start watchdog. I will try to send the same command from my downloading application.

I do not know, and if I did I would not disclose the workings of someone elses code
