| Zusammenfassung: | A real-time clock circuit, comprising: an oscillator; and a counter, coupled to an output of the oscillator, for generating a real-time clock value. In a first mode the oscillator is configured to generate oscillations and the counter is configured to increment the real-time clock value based on the oscillations. In a second mode the oscillator is stopped, and the counter is configured to retain the real-time clock value at a frozen value. |
