There are +alarms for high, low, and critical thresholds. There's also an hysteresis to +control the thresholds for resetting alarms. + +The driver also supports LM76 and Maxim MAX6633/MAX6634/MAX6635, which are +mostly compatible but do not have a vendor ID register and therefore must be +instantiated explicitly. |
