Functional overview

Note:

The RTC, the IWDG, and the corresponding clock sources are not stopped by entering Stop

mode.

Clocks and startup

System clock selection is performed on startup, however the internal RC 8 MHz oscillator is

selected as default CPU clock on reset. An external 4-32 MHz clock can be selected, in

which case it is monitored for failure. If failure is detected, the system automatically switches

back to the internal RC oscillator. A software interrupt is generated if enabled. Similarly, full

interrupt management of the PLL clock entry is available when necessary (for example on

failure of an indirectly used external crystal, resonator or oscillator).

Several prescalers allow the application to configure the frequency of the AHB and the APB

domains. The maximum frequency of the AHB and the APB domains is 48 MHz.
