The FR Family MCUs feature a sophisticated clock distribution scheme with the different clock sources such as RC Clock, Main Clock, PLL Clock, Modulated PLL Clock, and Sub Clock. The core and the peripherals are connected to different clock trees that can be connected to different clock sources and clock frequencies to allow for a fine-grained control over the required operation speed and power consumption.
