Note that from now on we will supply QCX chips with low fuse 0xD7 not 0xF7. The new recommendation will be 0xD7. The old F7 has a 65ms delay on start-up for slowly rising power line but this is NOT required when you are using a Brownout Detector bit since the brownout logic will hold the reset anyway until the power line comes up (ATmega328 datasheet). D7 removes the 65ms startup delay.
Dear Hans,

does incorporate the new fuse settings or do I have to manually fiddle with them when re-flashing an old chip?
I’m a total ATmega328 newbie running 1.00c firmware (OEM chip).
