Old Topics / Problem to program 89C61X2
June 17, 2004, 09:02:22 PM

I want to program 89C61X2. When I try to read security bits, Flash Magic has a message "Unable to connect at a specified baud rate. Try reducing the baud rate. Reset the hardware into ISP mode again." I already use the lowest baud rate. Why the MCU cannot be connected?

You can go to page 13
and page 17
to see my schematic.

Also, I connected pin2 of DB9-F to pin14 of MAX232,
pin3 of DB9-F to pin13 of MAX232,
pin5 of DB9-F to GND.

Hi, Andy

How can I send email to you? I don't know your email. Thanks.
