68 / 117 page  TUSB7320, TUSB7340 SLLSE76M – MARCH 2011 – REVISED JULY 2015 www.ti.com 7.5.2.13 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 Table 129.

Serial Number – Lower DW. The lower DW of the Serial Number is 31:0 SERIAL_NUM_LOWER r unique for each device. 7.5.3 xHCI Memory Mapped Register Space 7.5.3.1 The xHCI Register Map The TUSB73X0 includes xHCI registers in memory mapped register space. These registers are accessible through the address programmed into the Base Address Register 0/1.
