WAKE Testing Setup
The EVM board can be used to test the WAKE functionality of the TUSB73X0. By default, the EVM is not
configured to support wake testing. Please configure the EVM according to the following if WAKE is
required:
1. Move the Jumper Shunt on J40 to pins 2 and 3.
2. Make sure there is no Jumper Shunt on J22.
3. Use a dedicated 5-V power supply for VBUS. Do NOT use the IDE Power connector provided from the
system power supply. The reason for not using the IDE power from system power supply is when the
system is put in a sleep or hibernate state, the power on the IDE Power connector will be turned off.
NOTE:
For some motherboards, WAKE from a PCIe slot is not supported or is only supported on
PCIE X1 slots. Please make sure to use a motherboard that supports WAKE from any PCIe
slot.
