MSP430FR5969: UART maximum baudrate

Part Number: MSP430FR5969

Hi,

What is the maximum UART Baud rate can be generated in MSP430FR5969? As i tried, i can able to generate upto 921600bps, using 4MHz/8MHz as external clock.

Is it possible to generate 2Mbps in MSP430's UART?

Thanks in advance

    Hi Gayathri,

    The maximum bit clock (baud rate) is 4MHz.  The maximum clock speed into the eUSCI module is 16MHz.

    Using the 16MHz clock and a divisor of 8 in the UCAxBRW register will work, or if clocking @ 8MHz then a divisor of 4.
