Reset of ERROR registers and Disable
The TLE7183F can be reseted by the enable pins ENAx. If one or two ENAx pins is pulled to low for a specified
minimum time, the error registers are cleared and the external MOSFETs are switched off actively.
During disable only the errors undervoltage shut down and overtemperature warning are shown. Other errors are
not displayed.
