3-Phase Sine Wave Generator with Dead-Time Correction TPU Function Set (3SinDt) MOTOROLA
NOTE:
There is one limitation. The absolute value of parameter move has to be less
than a quarter of the PWM period T.
Execution times do not include the time slot transition time (TST = 10 or 14 IMB
clocks)
Parameter
move
presc_addr
prescaler
Other parameters are just for TPU function inner use.
