The function of the three

DRV_x_HSMC_RSLVR_DRV_HALL_QUAD_y

signals on the HSMC

changes according to the jumper settings for resolver (Table 15) and Hall effect and

quadrature (Table 16).

HSMC Isolator Power Supply

You may source the power supply for the host FPGA board side of the isolators

directly from the HSMC 3.3-V supply or derive it from the HSMC 12-V supply by a

switching regulator module (Table 17). This feature allows for situations where

insufficient power is available from one or the other of the HSMC supplies.
