If i am generating baud rate at 9570 or 9630, can i match the baud rate with 9600 device ( Eg: Modem or Hyperterminal PC). give suggestion B'coz i using internal x-tal, i can't create exact baudrate like 9600,19200..
 

Re: baud rate difference

The actual baud rate does not matter as long as all the equipment you are connecting to uses the same value. So if the device you are talking to is also 9570/9630 there will be no problem.

If you are talking to devices which are using the standard 9600 speed, the 'rule of thumb' is to stay within 2.5% of center speed. For 9600 bauds this means between 9365 and 9840 bauds so you might be OK. Please bear in mind that inaccuracy at the other end may also limit the acceptable range.

Brian.
