How to set MC9S08QE32 uart baud rate at 115200?

Hi,

I've a big problem.

I'm trying to setup my Xbee pro module via UART by AT command.

In the datasheet the default baudrate is 115200 so I'm trying to setup my MC9S08 uart to this, but I have this ERROR message:

"Time setting failed"

 

It only let me setup at 9600... how is possible?

I've used Processor Expert to setup the components.

Please Help!

Hi Gian Paolo,

You can get a 115200 Baudrate if you set the Internal oscillator frequency to 36 KHz and the Internal bus clock to 9.216 MHz:
