摘要： A clock generator in apparatus such as e.g. a microcontroller unit is calibrated by aligning at subsequent calibration times the frequency of a first clock (106) with respect to the frequency of a second clock (108) having a higher frequency accuracy than said first clock (106), with the frequency of the first clock (106) which h varies between subsequent calibration times. The frequency of the first clock (106) is aligned to a frequency which is offset by a certain amount with respect to the frequency of the second clock (108) in order counter frequency error which may accumulate over time due to the variation in the frequency of the first clock (106).
