37 / 58 page  AN3311 Getting started with the system Doc ID 18209 Rev 1 37/58 The clock distribution and the interrupt settings are two components that are strongly dependent on the target project. An example of clock rate may be 72 MHz as the maximum speed of the current STM32 microcontroller. It can be decreased to reduce the power consumption. The clock rate assumptions are: ● System HCLK - 72 MHz ● Low speed peripheral PCLK1 - 72 MHz ● High speed peripheral PCLK2 - 36 MHz ● Analog to digital converter ADCCLK - 36 MHz The interrupt setting situation is very similar to clock distribution. The library functions involved with interrupt managing do not take the priorities into account; they only perform very necessary and absolutely common settings to make them serviceable. |
