BF527 restart from hibernate

I am having problems getting a BF527 to restart from hibernate. When the restart signal on PG15 is asserted, VROUT asserts and the external core voltage regulator starts up, but then nothing more happens.


How quickly must the external core voltage regulator stabilize? In this design it takes about 800us, is that too long?


The 25MHz crystal is also taking around 800us to stabilize, is that a problem?
