The OCP, SSI interconnects, and static switches manage data transfers
between OMAP3.2 and the SSI or VLYNQ and USB peripherals.
The SSI is a full-duplex interface, using a synchronous serial interconnect
protocol (SSI). This protocol consists of a transmitter called (SST) in SSI,
which is in charge of transmitting information, and a receiver called (SSR),
which is in charge of receiving information
