Thread Summary

                The user asked which pins are latched during the power-on reset of the AD5421. The final answer confirmed that the AD5421 powers on with all registers loaded to default values, and the loop current is set to 3.2 mA or 22.8 mA/24 mA based on the ALARM_CURRENT_DIRECTION pin and selected range. The pins mentioned are input pins that set the part's configuration at power-on.
