Power Management Controller
The Power Management Controller provides all the clock signals to the system. It provides:
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 Device HS Clock UDPCK
independent peripheral clocks, typically at the frequency of MCK
three programmable clock outputs: PCK0, PCK1 and PCK2
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.
Figure 10-3.
Power Management Controller Block Diagram
The SysTick calibration value is fixed at 10500, which allows the generation of a time base of
1 ms with SystTick clock to 10.5 MHz (max HCLK/8).
