Note:
For (R/X)DATDLY = 0, the first bit of data transmitted is asynchronous to
CLKX, as shown in Figure 11–12.
The McBSP can be configured to ignore transmit and receive frame synchro-
nization pulses. The (R/X)FIG bit in the (R/X)CR can be set to 0 to recognize
frame sync pulses, or it can be set to 1 to ignore frame sync pulses. This way,
you can use (R/X)FIG either to pack data, if operating at maximum frame fre-
quency, or to ignore unexpected frame sync pulses.
