3 Quick Start Guide

The instructions below assume the EVM is configured for pin-strap mode and is powered from VBUS.

  1. Insertion USB-C plug side of EVM into the USB-C receptacle of the motherboard.
  2. Insertion USB-C cable or USB device into the USB-C receptable side of the EVM.
  3. The USB Device should enumerate. If USB device does not enumerate, suggest checking to make sure FLIP pin (JMP3) is set based on the CC pin orientation.

The instructions below assume the EVM is configured for I2C mode and is powered from barrel jack.

  1. Insertion +5 V DC Power source into barrel jack (J1).
  2. Configure TUSB1104 through the I2C interface via JMP4 and JMP5.
  3. Insertion USB-C plug side of EVM into the USB-C receptacle of the motherboard.
  4. Insertion USB-C cable or USB device into the USB-C receptable side of the EVM.
  5. The USB Device should enumerate. If USB device does not enumerate, suggest checking to make sure FLIP_SEL register is set based on the CC pin orientation.

Note: The TUSB1104 does not have a CC or PD controller. The CC pins from EVM's USB-C plug is routed directly to EVM's USB-C receptacle. It is important to make sure FLIP (JMP3), if in pin-strap mode, or FLIP_SEL register, if in I2C mode, is properly set.
