6.3.3 One-Time Programmable Configuration

The TUSB4041I-Q1 device allows device configuration through one-time programmable (OTP) non-volatile memory. The programming of the OTP is supported using vendor-defined USB device requests. Contact TI for details using the OTP features

Table 6-2 lists features that can be configured using the OTP.
