1. A clock control circuit, comprising:
a frequency tracking circuit;
a clock signal generation circuit coupled to the frequency tracking circuit; and
a control circuit coupled to the frequency tracking circuit and the clock signal generation circuit,
wherein the frequency tracking circuit is configured to track a frequency of a first signal from a host system,
the control circuit is configured to control the clock signal generation circuit to generate, in a first mode, a clock signal according to the frequency of the first signal, and
the control circuit is further configured to control the clock signal generation circuit to generate, in a second mode, the clock signal without reference to the frequency of the first signal.
