2. The reset network protects the device against parasitic resets.

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

Table 32. Otherwise the reset will not be taken into account by the device.

TIM timer characteristics

Unless otherwise specified, the parameters given in Table 33 are derived from tests

performed under ambient temperature, fPCLKx frequency and VDD supply voltage conditions

summarized in Table 7.

Refer to Section 5.3.12: I/O port pin characteristics for details on the input/output alternate

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