This bit is set by the HDLC controller when this buffer is the last in a frame. This implies
the reception of a closing flag or reception of an error, in which case one or more of the
CD, OV, AB, and LG bits are set. The HDLC controller will write the number of frame oc-
tets to the data length field.
This bit is set by the HDLC controller when this buffer is the first in a frame.

0 = The data buffer associated with this BD has been filled with received data, or data
1 = The data buffer associated with this BD is empty, or reception is currently in
0 = This is not the last buffer descriptor in the Rx BD table.
1 = This is the last buffer descriptor in the Rx BD table. After this buffer has been used,
0 = The RXB bit is not set after this buffer has been used, but RXF operation remains
1 = The RXB or RXF bit in the HDLC event register will be set when this buffer has

the E-bit is set, the CPU32+ core should not write any fields of this Rx BD.
the CP will receive incoming data into the first BD in the table (the BD pointed to
by RBASE). The number of Rx BD s in this table is programmable, and is deter-
mined only by the W-bit and the overall space constraints of the dual-port RAM.
