MSP430F2122: Error setting Baud Rate with MSP430F2122

Part Number: MSP430F2122


Hi all,

I am now using MSP430F2122 to create a new project.

In the past, I only used 9600bps as the baud rate in the project of the company.

Now I need to change the BR into 115200bps but the BR0 and BR1 registers can not be set to work in the setting.

I use SMCLK as the clock source of the UCA0 module.

SMCLK is 1MHz. I set BR0 as 8, and BR1 as 6.

It can not work.

With the same setting, I change the BR0 and BR1 into 104 and 0 with 9600bps can work.

I can not connect to BR calculation of TI.com.

Please help me the the problem.

Regards,

Norton
