The user selects the appropriate interfaces for an application during the boot

sequence. In effect, only a subset of all possible interfaces is available at

power-on reset. For flexibility, some interfaces are duplicated. See the pinout

section of the Application Processor Data Manual (SPRS231) to select the

desired configuration.

Table 53 provides an example of duplicated interfaces with the MMC/SDIO2.

The software programs (via the appropriate FUNC_MUX_CTRL register) the

desired configuration and ensures that no input/output is enabled twice.
