Figure 26. Recommended NRST pin protection
1. The reset network protects the device against parasitic resets.
2. The external capacitor must be placed as close as possible to the device.
3. The user must ensure that the level on the NRST pin can go below the V
IL(NRST)
max level specified in
Table 53. Otherwise the reset will not be taken into account by the device.
