3) If L1.2 time logging option is enabled, L1.2 Power could be 5mW.
4) Active/Idle/L1.2 Power are measured up to 1TB.

MTBF

MTBF is Mean Time Between Failure, and is the predicted elapsed time between inherent failures of a system during operation. As same word,
AFR (annual failure ratio) is 0.4%. MTBF can be calculated as the arithmetic average time between failures of a system.
