I want to use 8052 to control some hardware parts and want to save the data from RAM into EEPROM KM28c16. I tried the command "PROG" before and found that it had no response. I have seen the article in "http://www.8052.com/forum/read.phtml?id=4223&top=" and want to know what is the meaning of "internal timing registers". Did he mean of TH1 and TL1 in TIMER1? How can I set it to give plenty delays of time?
