5.12 Packet Forwarding Register n for 8-Bit Device IDs (PF_8B_CNTLn)
SRIO Registers
There are four of these registers (see
Table 54
). The general form of a packet forwarding register for
16-bit DeviceIDs is shown in
Figure 73
and described in
Table 55
. For additiona programming information
see
Section 2.3.15
and and
Section 2.3.15.3
.

OUT_BOUND_PORT
0–3
Output port number for packets whose DestID falls within the 8-bit or
16-bit range for this table entry.
15–8
8BIT_DEVID_UP_BOUND
00h–FFh
Upper 8-bit DeviceID boundary. DestID above this range cannot use
the table entry.
7–0
8BIT_DEVID_LOW_BOUND
00h–FFh
Lower 8-bit DeviceID boundary. DestID lower than this number cannot
use the table entry.
