A. For CLKRP = CLKXP = 1, the McASP transmitter is configured for falling edge (to shift data out) and the McASP
receiver is configured for rising edge (to shift data in).
B. For CLKRP = CLKXP = 0, the McASP transmitter is configured for rising edge (to shift data out) and the McASP
receiver is configured for falling edge (to shift data in).
