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)
Figure 10. svmStd_sync timing
prescaler
16-bit unsigned integer
The number of PWM periods per
synchronization pulse
– use in case of synchronized
prescalers change
The number of PWM periods per
synchronization pulse
– use in case of asynchronized
prescalers change
presc_copy
16-bit unsigned integer
Parameters written by TPU
Other parameters are just for TPU function inner use.
