Standard Space Vector Modulation with Dead-Time Correction TPU Function Set (svmStdDt)
Table 4
The CPU configures the TPU as follows.
1. Disables the channels by clearing the two channel priority bits on each
2. Selects the channel functions on all used channels by writing the
3. Initializes function parameters. The parameters T, prescaler, DT, MPW,
