    FSRP = FSXP = 1. As a SPI master, FSX is inverted to provide active-low slave-enable output. As a slave, the active-low signal input on FSX
    and FSR is inverted before being used internally.
    CLKXM = FSXM = 1, CLKRM = FSRM = 0 for master McBSP
    CLKXM = CLKRM = FSXM = FSRM = 0 for slave McBSP
    #
    FSX should be low before the rising edge of clock to enable slave devices and then begin a SPI transfer at the rising edge of the master clock
    (CLKX).
