7:0 | productIdLsb | RO/RW | Product ID LSB. Least significant byte of the product ID assigned by Texas Instruments and reported in the SuperSpeed Device descriptor. the default value of this register is 40h representing the LSB of the SuperSpeed product ID assigned by Texas Instruments 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 over-written to indicate a customer product ID.
Value used for this field will be the non-zero value written by EEPROM/SMBus to both PID and VID. If a zero value is written by EEPROM/SMbus to both PID and VID, then value used for this field will be the non-zero value from OTP. If a zero value is written by OTP, then value used for this field will be 40h . |
