C. Limits over operating temperature are guaranteed by design.
Note 3:
Guaranteed, but not 100% tested.
Note 4:
The SMBus logic block is a static design that works with clock frequencies down to DC. While slow operation is possible,
it violates the 10kHz minimum clock frequency and SMBus specifications and may monopolize the bus.
