Vendor ID LSB Register 7 6 5 4 3 2 1 0 vendorIdLsb[7] vendorIdLsb[6] vendorIdLsb[5] vendorIdLsb[4] vendorIdLsb[3:1] vendorIdLsb[0] R/RW-0 R/RW-1 R/RW-0 R/RW-1 R/RW-0 R/RW-1 Table 5. Vendor ID LSB Register Field Descriptions Bit Field Type Reset Description 7 vendorIdLsb[7] R/RW 0 Vendor ID LSB 6 vendorIdLsb[6] R/RW 1 Least significant byte of the unique vendor ID assigned by the USB-IF; the default value of this register is 51h representing the LSB of the TI Vendor ID 5 vendorIdLsb[5] R/RW 0 0451h. The value may be overwritten to indicate a customer vendor ID. 4 vendorIdLsb[4] R/RW 1 This field is R/W unless the OTP ROM VID and OTP ROM PID values are non- 3:1 vendorIdLsb[3:1] R/RW 0 zero. If both values are non-zero, the value when reading this register will reflect the OTP ROM value. 0 vendorIdLsb[0] R/RW 1 8.5.4 Vendor ID MSB Register Offset = 2h, reset = 04h Figure 5. Vendor ID MSB Register 7 6 5 4 3 2 1 0 vendorIdMsb[7:3] vendorIdMsb[2] vendorIdMsb[1:0] R/RW-0 R/RW-1 R/RW-0 Table 6. Vendor ID MSB Register Field Descriptions Bit Field Type Reset Description 7:3 vendorIdMsb[7:3] R/RW 0 Vendor ID MSB 2 vendorIdMsb[2] R/RW 1 Most significant byte of the unique vendor ID assigned by the USB-IF; the default value of this register is 04h representing the MSB of the TI Vendor ID 0451h. The value may be overwritten to indicate a customer vendor ID. 1:0 vendorIdMsb[1:0] R/RW 0 This field is R/W unless the OTP ROM VID and OTP ROM PID values are non-zero. If both values are non-zero, the value when reading this register shall reflect the OTP ROM value. 8.5.5 Product ID LSB Register Offset = 3h, reset = 40h Figure 6. Product ID LSB Register 7 6 5 4 3 2 1 0 productIdLsb[7] productIdLsb[6] productIdLsb[5:0] R/RW-0 R/RW-1 R/RW-0 Table 7. Product ID LSB Register Field Descriptions Bit Field Type Reset Description 7 productIdLsb[7] R/RW 0 Product ID LSB. 6 productIdLsb[6] R/RW 1 The default value of this register is 40h representing the LSB of the product ID assigned by TI. The value reported in the USB 2.0 device descriptor is the value of this register bit wise XORed with 00000010b. The value may be overwritten to indicate a customer product ID. 5:0 productIdLsb[5:0] R/RW 0 This field is R/W unless the OTP ROM VID and OTP ROM PID values are non-zero. If both values are non-zero, the value when reading this register will reflect the OTP ROM value. 16 Submit Documentation Feedback Copyright © 2015, Texas Instruments Incorporated Product Folder Links: TUSB4041I |
