Tim Timer Characteristics; Table 47. Timx Characteristics; Figure 20. Recommended Nrst Pin Protection - STMicroelectronics STM32L151CCT6 Manual

Electrical characteristics
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 V
Table 46. Otherwise the reset will not be taken into account by the device.
