12.3 DA – DA Register
Access: parallel interface, Read Only
Address: h36
Returns 8-bit value DA (hexadecimal) if the parallel port connection is good. Otherwise, returns some other
value indicating failure.
12.4 MBCR – Multicast Buffer Control Register
Access: parallel interface and I
2
C, Read/Write
Address: h00
12.5 FCBST – FCB BUFFER LOW THRESHOLD
Access: parallel interface and I
2
C, Read/Write
Address: h01
12.6 LPBT – Low Drop Precedence Buffer Threshold
Access: parallel interface and I
2
C, Read/Write
Address: h02
Bit [7:0]
MAX_CNT_LMT
Maximum number of
multicast frames allowed to
be buffered inside the
device at any one time
(Default = 80)
Bits [5:0]
BUF_LOW_TH
Buffer Low Threshold – the
number of free buffers
below which flow control or
WRED is triggered
(Default = 3F)
Bit 6
Use IP precedence subfield
(TOS[0:2]) for Transmission
Priority
(Default = 0)
Bit 7
Use IP precedence subfield
(TOS[0:2]) for Drop Level
(Default = 0)
Note that, for Bits 6 and 7, Default = 0 means to
use TOS[3:5].
Bits [7:0]
LOW_DROP_CNT
Number of frame buffers
reserved for low-drop traffic
(Default 3F)
