MSP430FR6922: UART is not working on 115200 baud rate

Part Number: MSP430FR6922

Hi all,
I have question regarding msp430 controller. I am working on msp430fr6922 controller. I have to set UARt communication baud rate on 115200. UART work on SMCLK frequency which is 4MHz. My question is what should be the value of UCOS16,UCBRFx,UCBRSx?? Please help because I couldn,t set baud rate on 115200 as I already follow Table 30-4, 30-5 as per mentioned in technical reference manual
Thank you.

  • Hi there,

    you can find recommended settings in table 30-5. So the value of OS16 should be 1,  UCBRFx should be 2, UCBRSx should be 0xBB.

    If the setting is correct, please check the config of BRCLK. You should config UCSSELx to connect BRCLK to SMCLK.
