Hi,
For power sequence of T2080, referred to "3.2 Power sequencing" of datasheet (pg: 48). Please suggest on the following:

"Before or after" means - not simultaneously. That is - USB_HVDD and USB_OVDD supplies should be either not applied, or already settled, when the USB_SVDD ramps up. Ramping up USB_HVDD and USB_OVDD simultaneously with USB_SVDD violate this requirement.
Section 3.2 states "PORESET_B input must be driven asserted and held during this step." meaning it must be asserted during power supplies ramp up.
Hello Alexander,
Thanks for your reply.
In case if USB section is not used in T2080, can voltages for USB_HVDD,USB_OVDD and USB_SVDD be unused or even unused voltage to be applied. Please confirm.

Mani
