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.

NAME
OFB2-0
DESCRIPTION
Offset Bits 2-0
. These three bits define the time it takes the Serial Interface receiver to
recognize and store the first bit of the serial input streams; i.e., to start assuming a new
internal frame. The input frame offset can be selected to be up to 4 CK clock periods from
the time when frame pulse input signal is applied to the FR input.

If frame input offset operation is not required, this register should be cleared by the CPU during system initialization.
Number of Clock Periods
Normal Operation. No bit offsetting.
