8.4.12.5 Motor Estimated Position by IPD
After inductive sense is executed, the rotor position is detected within 60 electrical degrees of resolution. The position is stored in register IPDPosition.
The value stored in IPDPosition corresponds to one of the six motor positions plus the IPD advance angle as shown in Table 8-8. For more information about IPD, see Section 8.4.3.5.2.
