TUSB8042: Use case of "HS_UP, SS_UP, HS_SUSPEND and SS_SUSPEND"

Takashi Onawa

Part Number: TUSB8042

Hi Team,

Could you tell me how "HS_UP, SS_UP, HS_SUSPEND and SS_SUSPEND" are used generally in USB hub system?
In order to use these output function, I need to attach USB host or EEPROM to write stsOutputEn to 1b.

Hi Onawa-san,

The HS_UP, SS_UP, HS_SUSPEND, SS_SUSPEND can be used as debug outputs or they can be used to drive LEDs to report status of the upstream port of the TUSB8042.

Yes, a SMBUS host or EEPROM is needed to enable the status mode.
