20130159747 | DATA PROCESSING APPARATUS AND METHOD FOR MAINTAINING A TIME COUNT VALUE - A counting circuit for a data processing apparatus has a normal mode in which a main counter increments the time count value in response to edges of a main clock signal, and a power saving mode in which the main clock signal is disabled and a further clock counter counts elapsed edges of a further clock signal having a lower frequency than the main clock signal. On switching to power saving mode, a reference time count value of the main counter is captured at a timing triggered by an edge of the further clock signal. On switching back to normal mode, an expected time count value from the main counter is calculated based on the captured reference value and the counted number of elapsed edges during the power saving mode, and the main counter is restarted at a timing triggered by another edge of the further clock signal. | 06-20-2013 |
