 Clock Management | |
  DFLL Management | A Digital Frequency Locked Loop can be used to generate a highly accurate frequency from a slower-running reference clock, in much the same way as a PLL |
| Generic Clock Management | Generic clocks are configurable clocks which run outside the system clock domain |
| Oscillator Management | This group contains functions and definitions related to configuring and enabling/disabling on-chip oscillators |
 System Clock Management | See Quick Start Guide for the System Clock Management service (UC3L) |
