3.3.3 UART Mode

In UART mode, the TUSB2E11 acts a UART to UART repeater to support in-system debug. UART mode can be entered by pulling the GPIO0 low when the TUSB2E11 is in I2C mode or by setting SCL high and SDA low at reset, and setting the GPIO0 low. If SCL is high and SDA is low at reset, and GPIO0 is pulled high, then the TUSB2E11 will be in a non-functional state.
