Dear All,
I am Ravikmar.N, working on Atmel (AT89C52)
microcontroller.

I know that TIMER1 of AT89C52 can be used to generate baudrate upto
57600.

I need to set the microcontroller to 38400 or 115200. I dont know what
values to be filled to the TIMERn register and which TIMERn to be used.


If anybody know the solution please share your knowledge with me.


Thanks in advance.

The datasheet will tell you exactly this.
