SIMULATE_FAULT will allow the user to simulate fault and warning conditions by triggering the output of the detection circuit for that controls it. Multiple faults and or 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 will only simulate while conversion is enabled to allow these faults to simulate repeated shut-down and restart responses when FAULT_PERSIST is selected.
