    Hi,
    If you are using SCI/LIN module formulas are:
    SCICLK Frequency = VCLK Frequency / (P + 1 + (M/16) );
    Async baud value = SCICLK Frequency / 16;
    If P = 0 then Acync baud value = VCLK Frequency / 32;

    More details on SCI/LIN module you can find in Section 29 of device TRM: www.ti.com/.../spnu563a.pdf

    If you are using SCI module then:
    Async baud value = VCLK Frequency / 16 * (BAUD + 1); where BAUD is prescaler value in BRS register
    for BAUD = 0, Async baud value = VCLK Frequency / 32

    More details on SCI module you can find under Section 30 of device TRM: www.ti.com/.../spnu563a.pdf

    Best regards,
    MIro
