Other Parts Discussed in Thread: TUSB7340

Hi,

My customer is asking about SMI output use case though SMI pin is floated in EVM. Can you give me some information of example use case?

Best Regards,

This pin is used when the BIOS requires to have Interrupt support on the TUSB7340.
The BIOS can use the TUSB7340's Register "USB Legacy Support Control/Status Register" to control this PIN and generate interrupts.
