Link Position in Buffer — RO. This field indicates the number of bytes that have been
received off the link. This register will count from 0 to the value in the Cyclic Buffer
Length register and then wrap to 0.
Cyclic Buffer Length — R/W. This field indicates the number of bytes in the complete
cyclic buffer. This register represents an integer number of samples. Link Position in
Buffer will be reset when it reaches this value.
Software may only write to this register after Global Reset, Controller Reset, or Stream
Reset has occurred. This value should be only modified when the RUN bit is 0. Once the
RUN bit has been set to enable the engine, software must not write to this register until
after the next reset is asserted, or transfer may be corrupted.
