Power Management Controller
Figure 10-2. Clock Generator Block Diagram
The Power Management Controller provides all the clock signals to the system. It provides:
The Supply Controller selects between the 32 kHz RC oscillator or the crystal oscillator. The
unused oscillator is disabled automatically so that power consumption is optimized.
By default, at startup the chip runs out of the Master Clock using the Fast RC Oscillator running
at 4 MHz.
• the Processor Clock HCLK
• the Free running processor clock FCLK
• the Cortex SysTick external clock
• the Master Clock MCK, in particular to the Matrix and the memory interfaces
• the USB OTG HS Clock UOTGCK
• independent peripheral clocks, typically at the frequency of MCK
• three programmable clock outputs: PCK0, PCK1 and PCK2
