There is one set of limits. -When the HOT Temperature Limit is crossed, this will cause an alarm that will -be reasserted until the temperature drops below the HOT Hysteresis. -Measurements are guaranteed between -55 and +125 degrees. The temperature -measurement has a resolution of 0.5 degrees; the limits have a resolution -of 1 degree. - -Voltage sensors (also known as IN sensors) report their values in volts. -An alarm is triggered if the voltage has crossed a programmable minimum -or maximum limit. Note that minimum in this case always means 'closest to -zero'; this is important for negative voltage measurements. All voltage -inputs can measure voltages between 0 and 2.55 volts, with a resolution -of 0.625 mV. - -If an alarm triggers, it will remain triggered until the hardware register -is read at least once. This means that the cause for the alarm may -already have disappeared by the time the alarm is read. The driver -caches the alarm status for each sensor until it is at least reported -once, to ensure that alarms are reported to user space. - -The ADC128D818 only updates its values approximately once per second; -reading it more often will do no harm, but will return 'old' values. - -In addition to the scanned address list, the chip can also be configured for -addresses 0x35 to 0x37. Those addresses are not scanned. You have to instantiate -the driver explicitly if the chip is configured for any of those addresses in -your system. |
