ABSTRACT:
A method is provided for configuring a microcontroller clock system that includes a main oscillator, a phase locked loop, and a backup oscillator. According to the method, the main oscillator and the backup oscillator are activated in reset mode. A clock signal is generated from the backup oscillator, and the clock signal that is generated is applied to the microcontroller in order to start the microcontroller. Also provided are a clock system for a microcontroller, and a microcontroller including a clock system.
