Product data sheet
With any one of the preceding events, the SAF1761 USB controller wakes-up from
suspend and the clock starts functioning, and all functionalities work normally.
When the SAF1761 is suspended for the second time, the clock stops and the SAF1761
enters into deep sleep mode but it cannot be woken-up again by any of the preceding
events. The clock is not getting started when the SAF1761 device gets connected to the
Host Controller (see
DC_SUSPEND/WAKEUP_N pin to go LOW, but the clock is not started. The clock never
turns on and the SAF1761 can never be resumed from the suspended state.
