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 9.
