Forced cutoff input
IDU, IDV, IDW
Position-data-retain function input
Notes:
1.
Set the port direction bits which share pins to 0 (input mode). When not using the three-phase
output forced cutoff function, input a high-level signal to the
SD
pin.
2.
Set the port direction bits which share pins to 0 (input mode).
The above diagram shows an example of U-phase.
