This delay is very conservative.
What's the meaning of conservative?
In this context it means safe.
It means 5ms delay long enough? or at least, FLL lock time should be ensured 5ms?
Yes, the 5ms should be more than enough time for the FLL to lock - in most situations the time taken to do the register writes surrounding enabling and then using the FLL are sufficient to cover the startup time.
OK, I have a one more question. Is there any checking method for locking FLL? (ex. Checking register bit for FLL lock) Just using msleep looks not enough to ensure FLL lock.
