Detailed Description

UARTUSCIA Baudrate configuration.

This structure is used to specifiy the usci controller's clock divider settings to achieve the desired baudrate given the indicated clock input frequency. Divider values can be determined by referring to the MSP430 baudrate calculator. https://software-dl.ti.com/msp430/msp430_public_sw/mcu/msp430/MSP430BaudRateConverter/index.html

A sample structure is shown below:

const UARTUSCIA_BaudrateConfig uartUSCIABaudrates[] = {
 // Baudrate, input clock (Hz), Prescalar, UCBRFx, UCBRSx, oversampling
    {
        .outputBaudrate = 115200,
        .inputClockFreq = 8192000,
        .prescalar = 4,
        .hwRegUCBRFx = 7,
        .hwRegUCBRSx = 0,
        .oversampling = 1
    },
    {9600,    8192000,          53,        5,      0,      1},
    {9600,    32768,            3,         0,      3,      0},
};
