Hi Brian-san,

Thank you for your support.

Also, thank you for responding via private message.

Would it be possible to provide materials other than the information listed on the data sheet?

Hi Brian-san,

When the customer performed a USB 3.0 compliance test for an application that implemented TUSB8041, they changed the OTP settings to pass the test. The documentation regarding the OTP setting details and the writing tool had not been made public, so we are making this request.

Best Regards,

Hi Brian-san,

I changed the Pre-emphasis setting in the TUSB80xx_eFuse_Programming_Tool.

However, I don't know which register was changed, so I would like to know the details of the OTP.

The USB compliance test failed, so I changed the Pre-emphasis to pass it.

Hi Brian-san,

Thank you for your support.

When you say "Row 18," am I correct in understanding that you mean the item marked as 18 in rows D and E of Sheet "FROM_8041"?

Best Regards,

Nishie
