Cant connect 89C51RD2xx

[Nikhil]

whenever i start flashmagic i get the following error..

Unable to read the security bits and clocks bit. the security bit and 6clks/cycle may not reflect the actual settings of the device. to read the security and clock bits connect the device to the selected com port and place it into bootrom and then click retry button.


and whn i try to connect ... it says cannot connect at the specified rate try reduce rate. reset the hardware in isp mode again.


does the bootrom gets erased if whn full flash erase is implemented??

if so what shud be done..

hope u understand my prob!
