Description of Modes, Protection and Diagnostic Functions
Reset of error registers and Disable
The TLE7184F-3V can be reset by the enable pin RGS. If the RGS pin is pulled to low for a specified minimum
time, the error registers are cleared. If the error is still existing when the RGS pin is pulled to low, no reset will be
performed and the ERR pin stays low.
