Blackfin and Hibernation: simple question with no answer

My BF548 wakes up from hibernation on an RTC interrupt.

EXT_WAKE signal turns on a separate switching regulator of blackfin’s internal voltage and turns on the clock generator as well.


But nowhere in the datasheets I could not find, HOW MUCH time I’ve got to stabilize the core voltage and to start up the clock generator before a kind of internal reset will be released?
