Specifications to -40°C are guaranteed by design and are not production tested.
Typical value presented for reference only. Do not draw current from this pin.
FLL disabled. Crystal connected across HFXIN and HFXOUT. Operating in divide-by-1 mode. Measured on the DVDD pin
and part executing program code from flash. All inputs are connected to GND or DVDD. Outputs do not source/sink any
current. Timer B enabled.
