8.2.13 Device Serial Number Register
This read-only register identifies the Device Serial Number for the TUSB73x0. The Device Serial Number is
in the format of an IEEE defined 64-bit extended unique identifier (EUI-64). The EUI-64 consists of TI’s 24-bit
company ID (called an OUI-24) plus a 40 bit extension identifier. TI’s OUI-24 is 080028h and is hardwired into
bits 63:40 of the Device Serial Number Register. The TUSB73x0 has been assigned the range of 00 0000 0000h
to 00 0FFF FFFFh for the 40-bit extension identifier. As such, bits 39:32 of the Device Serial Number Register
are hardwired to 00h, and bits 31:0 of the Device Serial Number Register are defined by a value unique for each
device.
PCI Express Extended Register Offset: 154h
Register type: Read-Only
Default value: 0800 2800 XXXX XXXX h
