Hi I have aprogram that runson p89c51 and p89v51 when I am usunf an exact baudrate divider. I had to change my crystal and I have 3% error. the p89c51 keeps working fine and the p89v51 works in an unexpected way. Does someone experienced such a problem?
Thanks! with timer 2 it works. (0.49% error)
It means that we should not take for granted that the p89v51 is 1 to 1 substitute for the p89c51...
NO, It means that we should not take for granted that ANY 'identical' chip is 1 to 1 substitute for the p89c51 when running outside margins
