Advanced features for motor control

The slave mode controller is configured in reset mode; the slave input is TI1F_ED. Thus,

each time one of the 3 inputs toggles, the counter restarts counting from 0. This creates a

time base triggered by any change on the Hall inputs.

Channel 1 is configured in input capture mode, capture signal is TRC. The captured value,

which corresponds to the time, elapsed between 2 changes on the inputs, gives information

about motor speed.

TIM configuration in Hall sensor interface mode

Configure 3 timer inputs ORed to the TI1 input channel by writing the TI1S bit in CR2

Program the time base: write the ARR to the max value (the counter must cleared by

the TI1 change. Set the prescaler to get a maximum counter period longer than the

time between 2 changes on the sensors,

Program channel 1 in capture mode (TRC selected): write the CC1S bits in the CCMR1
