Figure 36. Recommended NRST pin protection

1. The reset network protects the device against parasitic resets.

2. The user must ensure that the level on the NRST pin can go below the VIL(NRST) max level specified in the above table.

Otherwise the reset is not taken into account by the device.

3. The external capacitor on NRST must be placed as close as possible to the device.

5.3.16

Extended interrupt and event controller input (EXTI) characteristics

The pulse on the interrupt input must have a minimal length in order to guarantee that it is

detected by the event controller.
