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.
