| 115 116.. note:: 117 118 - Configure `shunt_resistor` before configure `power1_crit`, because power 119 value is calculated based on `shunt_resistor` set. 120 - Because of the underlying register implementation, only one `*crit` setting 121 and its `alarm` can be active. Writing to one `*crit` setting clears other 122 `*crit` settings and alarms. Writing 0 to any `*crit` setting clears all 123 `*crit` settings and alarms. |
