5.11 Packet Forwarding Register n for 16-Bit Device IDs (PF_16B_CNTL n)
SRIO Registers
There are four of these registers (see Table 52 ). The general form of a packet forwarding register for
16-bit DeviceIDs is shown in Figure 72 and described in Table 53 . For additional programming
information, see Section 2.3.15 and Section 2.3.15.3 .

Bit Field Value Description
31–16 16BIT_DEVID_UP_BOUND 0000h–FFFFh Upper 16-bit DeviceID boundary. DestID above this range
cannot use the table entry.
15–0 16BIT_DEVID_LOW_BOUND 0000h–FFFFh Lower 16-bit DeviceID boundary. DestID lower than this
number cannot use the table entry.
