| 84 | The LM73 features a simple over-temperature alarm mechanism. This | ||
| 85 | feature is exposed via the sysfs attributes. | ||
| 86 | |||
| 87 | The attributes 'temp1_max_alarm' and 'temp1_min_alarm' are flags | ||
| 88 | provided by the LM73 that indicate whether the measured temperature has | ||
| 89 | passed the 'temp1_max' and 'temp1_min' thresholds, respectively. These | ||
