8.10 XY Alignment

The P9415 has integrated XY alignment coil data receive circuitry that should be used to monitor XY alignment coils integrated with the WPC

TRx coil. The XY alignment feature allows the device to sense its relative position to the Tx coil magnetic field center and enables FOD

compensation to be applied based on the position of the Rx to increase spatial freedom. When used, the XY alignment coils should be connected

to pins GP4 (X-alignment coil input) and GP5 (Y-alignment coil input).
