CCS/MSP430F5659: UART baud rate setting

Part Number: MSP430F5659

Tool/software: Code Composer Studio

Hello Everyone,

I am using msp430f5659 interfacing with ESP8266 Module , Using Uart Protocol, I have set the baud rate (115200) at UCA2BR0=9  according to data sheet at 1.04 MHZ. Every thing works fine.

my problem start with when i used to set my DCO frequency with 25 MHZ for LCD interfacing using SPI Protocol, 

My LCD and SPI part works successfully but my ESP8266 Doesn't respond when i set DCO at 25MHZ its only show some garbage results and sometimes it doesn't show even garbage.

So can anyone suggest me how can i set my UART part at 1.04 Mhz and rest of the part at 25Mhz. or tell me something other better options.

Best Regards

Vikash Raman
