SIMULATE_FAULT allows the user to simulate fault and warning conditions by triggering the output of the detection circuit for that controls it. Multiple faults can be simulated at once.

*Only SIM_VIN_OFF and SIM_VOUT_OVF are allowed to trigger their analog comparator while conversion is disabled. All other faults, including SIM_TEMP_OTF and SIM_VIN_OVF, only simulate while conversion is enabled to allow these faults to simulate repeated shutdown and restart responses when FAULT_PERSIST is selected.
