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.
