32.3.3 Clock Frequency and Clock Switching

The dsPIC33AK128MC106 family devices allow a wide range of clock frequencies to be selected under application control. If the system clock configuration is not locked, users can choose low-power or high-precision oscillators by setting NOSCx bits (OSCCON[10:8]) and setting the OSCSWEN bit, as well as addressing any CLKxDIV changes required.. The process of changing a system clock during operation, as well as limitations to the process, are discussed in more detail in Oscillator and Clocking Module.
