13.18.1 Fault Clearing State

The OE pin is used to clear any Faults and re-enable the driver. After toggling the OE pin low-to-high, the system requires a minimum time period to re-enable and start up all of the driver blocks. The start-up time is approximately 35 μs. The maximum pulse time for the high-low-high transition to clear the Faults should be less than 900 μs to prevent the system from transitioning through Standby mode. If the high-low-high transition is longer than 1 ms, the device will start up from the Standby state.

Any Fault status bits that are set will be cleared by the low-to-high transition of the OE pin, if and only if, the Fault condition has ceased to exist. If the Fault condition still exists, the active Fault status bit will remain active. No additional Fault messages will be sent for a Fault that remains active.
