29.1 Clock Frequency and Clock Switching

The dsPIC33CK512MPT608 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 simply changing the NOSCx bits (OSCCON[10:8]). The process of changing a system clock during operation, as well as limitations to the process, are discussed in more detail in Oscillator with High-Frequency PLL.
