1: Frames with measured lengths shorter than their length fields are discarded. Frames containing a type ID in bytes 13 and 14
(length/type ID = 0600) are not be counted as length errors.
• RBOF: Receive Buffer Offset
Indicates the number of bytes by which the received data is offset from the start of the first receive buffer.
