There are two modes for the McBSP3, which are selected by the bit 28,
MOD_MCBSP3_MODE_R, of the MOD_CONF_CTRL_0 register:
-
MOD_MCBSP3_MODE_R = 0 (default). In this case, the McBSP3 is half
duplex, master for transmission, slave for reception. The paths shown as
dashed lines in Figure 9–5 are not available in this mode. Table 9–11 lists
the McBSP3 signals available in this mode at the OMAP5910 level.

-
MOD_MCBSP3_MODE_R = 1. In this case, the McBSP3 is half duplex,
master/slave for transmission, slave for reception. This mode utilizes the
paths shown as dashed lines in Figure 9–5. Table 9–12 lists the McBSP3
signals available in this mode at the OMAP5910 level.
