IDT PES48H12G2 Device Overview
Notes
PES48H12G2 User Manual
System Identification
Vendor ID
All vendor IDs in the device are hardwired to 0x111D which corresponds to Integrated Device Tech-
nology, Inc.
Device ID
The PES48H12G2 device ID is shown in Table 1.2.
Revision ID
The revision ID in the PES48H12G2 is set to the same value in all mode. The value of the revision ID is
determined in one place and is easily modified during a metal mask change. The revision ID will start at 0x0
and will be incremented with each all-layer or metal mask change.
Revision ID
0x0
0x1
0x2
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 PES48H12G2 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 capability, 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 PES48H12G2 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 capa-
bility if necessary.
