UART baud rate at 6MHz

UART baud rate at 6MHz

2004-03-24 by Chetan Bhargava

Hi All,

I'm running AT90S2313 at 6MHz. I calculated the UBRR value to be 38 
for baud 9600. The actual baud would be 9615.38 would that be okay 
according to the RS232 standards?

Regards,

Chetan

You're allowed some error, but both sides have to split the allowable error.
You're way under at less than 1% error.
