NOTE:
3Sin with Dead-Time Correction – XOR version TPU Function Set (3SinDtXor)
PWM period T has to be greater. Get all the other running function states that
can be served during one PWM period. Get their lengths (number of IMB clock
cycles) and add a time slot transition of 10 IMB clock cycles to each one. Sum
all the states lengths including the time slot transition. Convert the result from
IMB clock cycles to TCR1 clock cycles according to TCR1 prescaler settings.
The result indicates how much greater than the minimum value of 525 T has to
be for that particular case.
Execution times do not include the time slot transition time (TST = 10 or 14 IMB
clocks)
