5.12 Packet Forwarding Register n for 8-Bit Device IDs (PF_8B_CNTL n)
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 .

31–18 Reserved 0 Reserved
17–16 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.
