IDT PES64H16G2 Device Overview

System Identification

Vendor ID

All vendor IDs in the device are hardwired to 0x111D which corresponds to Integrated Device Technology, Inc.

Device ID

The PES64H16G2 device ID is shown in Table 1.2.

Revision ID

The revision ID in the PES64H16G2 is set to the same value in all mode. The value of the revision ID is determined in one place and is easily modi-
fied during a metal mask change. The revision ID will start at 0x0 and will be incremented with each all-layer or metal mask change.

JTAG ID

The JTAG ID is:
– Version: Same value as Revision ID. See Table 1.3
– Part number: Same value as base Device ID. See Table 1.2.
– Manufacture ID: 0x33
– LSB: 0x1

SSID/SSVID

The PES64H16G2 contains the mechanisms necessary to implement the PCI-to-PCI bridge Subsystem ID and Subsystem Vendor ID capability
structure. However, in the default configuration the Subsystem ID and Subsystem Vendor ID capability structure is not enabled. To enable this capa-
bility, the SSID and SSVID fields in the Subsystem ID and Subsystem Vendor ID (SSIDSSVID) register must be initialized with the appropriate ID
values. the Next Pointer (NXTPTR) field in one of the other enhanced capabilities should be initialized to point to this capability. Finally, the Next
Pointer (NXTPTR) of this capability should be adjusted to point to the next capability if necessary.

Device Serial Number Enhanced Capability

The PES64H16G2 contains the mechanisms necessary to implement the PCI express device serial number enhanced capability. However, in the
default configuration this capability structure is not enabled. To enable the device serial number enhanced capability, the Serial Number Lower
Doubleword (SNUMLDW) and the Serial Number Upper Doubleword (SNUMUDW) registers should be initialized. The Next Pointer (NXTPTR) field in
one of the other enhanced capabilities should be initialized to point to this capability. Finally, the Next Pointer (NXTPTR) of this capability should be
adjusted to point to the next capability if necessary.
