Synchronized Change

of PWM Prescaler

And Resolver

Reference Signals

Prescaler

The svmStd3Xor_res TPU function can inherit the Synchronization Signal

prescaler that is synchronously changed with the PWM prescaler. Write the

synchronization signals presc_copy parameter address to the presc_addr

parameter to enable this mechanism. Write 0 to disable it, and in this case set

the prescaler parameter to directly specify prescaler value.
