Abstract: The disclosure provides a microcontroller which has an internal timing device for generating an internal clock signal, at least one terminal contact for receiving an external clock signal, a clock changing device and a timer module, which is electrically conductively connected to the at least one terminal contact and to the internal timing device and, after the microcontroller has been switched on, is set up to determine a frequency of the external clock signal by means of the clock signal, and to determine at least one parameter by means of which the clock changing device can be set up to change the external clock signal into a useful clock signal with a predefined frequency.

Abstract: A modulator operable to control an oscillator is described. The modulator can include a memory that stores oscillator control values and a bit streaming block. The bit streaming block can generate a bit stream based on the oscillator control values and transmit the bit stream to the oscillator to control an oscillation frequency of the oscillator. The modulator can also include a bit streaming loader (BSL). The BSL can receive one or more of the oscillator control values from the memory, generate one or more corresponding bit values based on the one or more of the oscillator control values, and provide the one or more bit values to the bit streaming block. The bit streaming block can then generate the bit stream based the one or more bit values generated by the BSL.
