Figure 12: HSE clock source timing diagram

Figure 13: Typical application with 8 MHz crystal

In the application, the resonator and the load capacitors have to be placed as close as

possible to the oscillator pins in order to minimize output distortion and startup stabilization

time. The REXT value depends on the crystal characteristics (refer to the crystal resonator

manufacturer for more details on them).

Advanced-control timer (TIM1)

The advanced-control timer (TIM1) can be seen as a three-phase PWM multiplexed on six

channels. It has complementary PWM outputs with programmable inserted deadtimes.

This timer is used to generate the PWM signal for the three half-bridge gate drivers as

shown in Table 10: "TIM1 channel configuration".
