Force RX Discard (RX_DUMP).
This self-clearing bit clears the RX data
and status FIFOs of all pending data. When a ‘1’ is written, the RX data
and status pointers are cleared to zero.
Note:
Please refer to section “Force Receiver Discard (Receiver
Dump)” on page 59 for a detailed description regarding the use
of RX_DUMP.

RX Data Offset (RXDOFF).
This field controls the offset value, in bytes,
that is added to the beginning of an RX data packet. The start of the valid
data will be shifted by the number of bytes specified in this field. An offset
of 0-31 bytes is a valid number of offset bytes.
Note:
The two LSBs of this field (D[9:8]) must not be modified while
the RX is running. The receiver must be halted, and all data
purged before these two bits can be modified. The upper three
bits (DWORD offset) may be modified while the receiver is
running. Modifications to the upper bits will take affect on the
next DWORD read.
