#175308 - BAUD RATE SETTING
Responding to: ???'s previous message
I am using NXP's P89V51RD2BN. Now what is the maximum frequency of crystal i can use( that is available in market) 40 is it's maximum limit. I also have to set the baud rate at 9600 so please suggest accordingly.

As Erik earlier said "use multiples of 11,0592" so i get maximum of 11.0592*3=33,17766.

I also saw at the keil Baudrate calculator that at this frequency i will get an error of -0,18% for 9600.

Can't use anything of a higher frequency without sacrificing the accuracy ?
