MCASP[x]_ACLKR/X (CLKRP = CLKXP = 1)

(A)

MCASP[x]_ACLKR/X (CLKRP = CLKXP = 0)

(B)

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).

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).
