Empty, written by the eTSEC (when cleared) and by the user (when set).
0 The data buffer associated with this BD is filled with received data, or data reception is aborted due
1 The data buffer associated with this BD is empty, or reception is currently in progress.
Receive software ownership bit.
This field is reserved for use by software. This read/write bit is not modified by hardware, nor does its
value affect hardware.
Wrap, written by user.
0 The next buffer descriptor is found in the consecutive location.
1 The next buffer descriptor is found at the location defined in RBASE.
Interrupt, written by user.
0 No interrupt is generated after this buffer is serviced.
1 IEVENT[RXB] or IEVENT[RXF] are set after this buffer is serviced. This bit can cause an interrupt
Last in frame, written by the eTSEC.
0 The buffer is not the last in a frame.
1 The buffer is the last in a frame.
First in frame, written by the eTSEC.
0 The buffer is not the first in a frame.
1 The buffer is the first in a frame.
Reserved
Miss, written by the eTSEC. (This bit is valid only if the L-bit is set and eTSEC is in promiscuous mode.)
This bit is set by the eTSEC for frames that were accepted in promiscuous mode, but were flagged as
a “miss” by the internal address recognition; thus, while in promiscuous mode, the user can use the
M-bit to quickly determine whether the frame was destined to this station.
0 The frame was received because of an address recognition hit.
1 The frame was received because of promiscuous mode.

if enabled (IMASK[RXBEN] or IMASK[RXFEN]). If the user wants to be interrupted only if RXF
occurs, then the user must disable RXB (IMASK[RXBEN] is cleared) and enable RXF
(IMASK[RXFEN] is set).
