Hi We are using MPC5554 and eTPU. In one of our applications for BLDC motor controller which is driven through SVM logic. As suggested by freescale we are writing alpha and beta parameters to eTPU parameter ram by dividing by 4. I am new to the team and not sure why this is required to be divided by 4. On the eTPU side the duty cycles are computed by using SVM. Can you please let me know why do we have to divide the alpha and beta values by 4.
