208/311
DS12903 Rev 2
Figure 38. 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
Table 74: NRST pin characteristics. 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.
6.3.16
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.
