The RC oscillator contains an error in the calibration routine that statistically occurs in 17.3% of all calibrations performed. When the calibration error occurs the RC oscillator tolerance is typically +8% (+10% expected worst case) to -0.3%. This means that the Wake-On-Radio (WOR) function will exhibit degraded performance in certain aspects or not be able to operate as intended. The following issue must be expected: • Increased average current consumption, since the necessary time needed in receive mode will increase due to the increased tolerance.
