I want to use Philips P89C51RD2BN on mon51 or isd51. 2 questions that I needed to support are: 1. Hardware electric circuit flow requirements. Below is the circuit flow chart that I created. I believe there are some errors. I would like you verify and let me know where these errors are. http://myweb.hinet.net/home10/january/1.JPG 2. should the source code be entered or keyed in to P89c51rd2bn THANK
Did you download the example into the on-chip Flash ROM of this device (for example by using FlashMagic)?
i did use your on-chip flash ROM for this device (generic 8052 example) . but still didn't work (I am using the 12MHz cystal) THANK
