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:
RESERVED
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.
