Clock Sources
Figure 9-1.
The clock sources are divided in two main groups: internal oscillators and external clock
sources. Most of the clock sources can be directly enabled and disabled from software, while
others are automatically enabled or disabled, depending on peripheral settings. After reset, the
device starts up running from the 2MHz internal oscillator. The other clock sources, DFLLs and
PLL, are turned off by default.
The internal oscillators do not require any external components to run. For details on character-
istics and accuracy of the internal oscillators, refer to the device datasheet.
