Figure 45. 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 V
IL(NRST)
max level specified in
Table 52. Otherwise the reset will not be taken into account by the device.
5.3.16 TIM timer characteristics
The parameters given in Table 53 are guaranteed by design.
Refer to Section 5.3.14: I/O port characteristics for details on the input/output alternate
function characteristics (output compare, input capture, external clock, PWM output).
