Figure 20. Recommended NRST pin protection

1. The reset network protects the device against parasitic resets. 0.1 uF capacitor must be placed as close as

possible to the chip.

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

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

TIM timer characteristics

The parameters given in Table 47 are guaranteed by design.

Refer to Section 6.3.13: I/O port characteristics for details on the input/output alternate

function characteristics (output compare, input capture, external clock, PWM output).

Table 47. TIMx(1) characteristics

1. TIMx is used as a general term to refer to the TIM2, TIM3 and TIM4 timers.
