E.1.1.4.1 Receive BD Control/Status Word. To initialize the buffer, the user should write
bits 15-12 and clear bits 11-10 and 5-0. The IMP clears bit 15 when the buffer is closed and
sets bits 5-0 depending on which error occurred.
E—Empty
X—External Buffer
W—Wrap (final BD in table)
I—Interrupt (The RXF bit in the event register is set when a complete frame is received,
independent of the I bit.)
L—Last in Frame
F—First in Frame
Bits 9–6—Reserved for future use
LG—Rx Frame Length Violation
NO—Rx Nonoctet Aligned Frame
AB—Rx Abort Sequence
MOTOROLA
0 = This data buffer is full or has been closed due to an error condition.
1 = This data buffer is empty; must be set by the user to enable reception into this buff-
0 = The data buffer associated with this BD is in internal dual-port RAM.
1 = The data buffer associated with this BD is in external memory.
0 = This is not the last BD in the receive BD table.
1 = This is the last BD in the receive BD table.
0 = The RXB bit in the event register is not set when this buffer is closed.
1 = The RXB bit (or RXF bit, if this is the last buffer in a frame) in the event register is
0 = This buffer is not the last buffer in a frame.
1 = This buffer is the last buffer in a frame.
0 = This buffer is not the first buffer in a frame.
1 = This buffer is the first buffer in a frame.
0 = No frame length violation occurred.
1 = A frame length violation was detected. Up to the number of bytes specified in the
0 = An octet aligned frame was received.
1 = A nonoctet aligned frame was received.
0 = No abort was received.
1 = A minimum of seven ones was received during frame reception.
