DESCRIPTION
Stream Pair A selection
. These three bits define which pair of streams are going to be connected
to the switch matrix, together with the permanently connected streams
STi0-1 / STo0-1.

These bits are only used when the Switching Configuration bits enable stream pair selection capability (SCB 1-0 =10) and the Input Data Rate Selection bits
enable 2 Mb/s operation (IDR-0 = 00). In all other modes, the contents of this register are ignored.
