Reset of ERROR registers and Disable
The TLE7189QK can be reseted with the help of the enable pin ENA. If the ENA pin 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 under voltage shut down and over temperature warning are shown. Other errors are
not displayed.
