2.1 Setup

Table 2-1 lists the headers provided for the configuration of the TUSB1146-Q1 by default. The configuration settings must be optimized depending on the amount of loss of each channel in the system. The EVM is configured to GPIO mode by default. If I2C configuration is desired, then the JMP37 (I2C_EN) shunt must be changed.
