1.Q: What is the system clock. What is a clock system.
A: Usually referred to as the system clock refers to the clock system, which is the oscillator (signal source), timing wake-up, frequency divider and other components of the circuit. The commonly used signal sources are crystal oscillators and RC oscillators.
