User should ensure a proper filtering of its power supply: a ferrite bead, connected to a shunt capacitor to the ground (10uF typically) is a good practice. 3.3 Clocking 3.3.1 Module Clocking The Cortex M0 microcontroller is clocked by its own High Speed Internal (HSI) RC oscillator. The HSI oscillator delivers a 8MHz clock reference. The microcontroller can run at 48MHz through the PLL.

Note that the signal is floating and not filtered on the module. The reset signal should be pulled up and filtered with a shunt capacitor (typically 100nF) to the ground. To ensure a proper reset of the cortex-M0 microcontroller, the reset signal should remain low for at least 10ms.
