GDU Desaturation Level Register Field DescriptionsField Description7GDSFHSGDU Desaturation Filter Characteristic for High-Side Drivers — This bit adjusts the desaturation filtercharacteristic of the three high-side FET pre-drivers. These bits cannot be modified after GWP bit is set. SeeSection 18.4.5, “Desaturation Error.6:4GDSLHSGDU Desaturation Level for High-Side Drivers — These bits adjust the desaturation levels of the high-sideFET pre-drivers. These bits cannot be modified after GWP bit is set. See Section 18.4.5, “Desaturation Error000 V desaths = VHD - 0.35V (typical value)001 to 110 see device electrical specification111 V desaths = VHD - 1.40V (typical value)3GDSFLSGDU Desaturation Filter Characteristic for Low-Side Drivers — This bit adjusts the desaturation filtercharacteristic of the three low-side FET pre-drivers. These bits cannot be modified after GWP bit is set. SeeSection 18.4.5, “Desaturation Error.2:0GDSLLSGDU Desaturation Level for Low-Side Drivers — These bits adjust the desaturation level of the low-side FETpre-drivers. These bits cannot be modified after GWP bit is set. See Section 18.4.5, “Desaturation Error000 V desatls = 0.35V (typical value)001 to 110 see device electrical specification111 V desatls = 1.40V (typical value)
