AN2533/D

16

Standard SVM – 3 outputs version – XOR version TPU Function Set (svmStd3Xor)

MOTOROLA

Performance

There is one limitation. The absolute value of parameter move has to be less

than a quarter of the PWM period T.

NOTE:

Execution times do not include the time slot transition time (TST = 10 or 14 IMB

clocks)

presc_copy

16-bit unsigned integer

The number of PWM periods per

synchronization pulse

– use in case of asynchronized
