The phase commutation has to be done according to hall sensors value. HallA, HallB and HallC
are connected to external interrupt sources or to the three internal comparators. The compara-
tors generate the same type of interrupts as the external interrupts.
microcontroller I/O ports are used in the starter kit.

Vm’ is implemented but not used. It can be used to get the value of the DC bus voltage.
The outputs UH, UL, VH, VL, WH & WL are used to control the power bridge. As previously
seen, they depend on the Power Stage Control (PSC) which generates PWM signals. For such
applications, the recommended mode is the Center Aligned Mode (see
POCRnRA is used to adjust ADC synchronization for current measurement.
