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 with

failure of an indirectly used external oscillator).

Several prescalers allow to configure the AHB frequency, the high speed APB (APB2) and

the low speed APB (APB1) domains. The maximum frequency of the AHB and the high

speed APB domains is 72 MHz, while the maximum allowed frequency of the low speed

APB domain is 36 MHz.

The advanced clock controller clocks the core and all peripherals using a single crystal or

oscillator. To achieve audio class performance, an audio crystal can be used.
