Abstract
In an embodiment a method includes generating a low-frequency clock signal having a first frequency, in a standby mode and in a run mode of the CPU, generating a high-frequency clock signal having a second frequency higher than the first frequency, in the run mode, updating a value of the reference time base at each period of the low-frequency clock signal in the standby mode, and accessing the counter register with the high-frequency clock signal in the run mode.
