To enable current limit mode, ensure that HICCUPEN = 0 in the CONTROL1 register.

When current limit operation is enabled, the device limits the high-side switch current cycle-by-cycle for as long as the overload condition exists. If the device limits the high-side switch current for four or more consecutive switching cycles, the device sets ILIM = 1 in the STATUS register.

The device clears the ILIM bit if the user reads the STATUS register when the overload condition no longer exits.
