Reserved. In normal functional mode, these bits MUST be set to zero.
Input Stream Inversion
For normal operation, this bit is set low.
To invert the input stream, set this bit high.
Input Sampling Point Delay
Default Sampling Point is 3/4. Adjust according to Figure 5 on page 20.
Input Stream Bit Rate
Unused streams must be connected to ground.
If the internal system clock is used as the clock source, all the above data rates are
available. Otherwise, the data rate cannot exceed the selected clock source’s rate.
