The clock module contains the internal and external oscillators, the clock monitors, and the clock selection and control logic. A frequency clock counter is also provided for checking and/or calibrating the frequency of high-speed clocks against either the LFXT/LFCLK_IN or a reference period/pulse provided on an IO pin.
Normally, the clock source and clock frequency will highly affect the system power consumption. As the SYSCTL will control the clock source switching between different power modes, users only need to select suitable oscillator clock sources for clocks, and use clocks with limited frequency range according to their typical application. The simplified CKM is shown in Figure 2-3.
