45 16 general purpose digital I/O lines, eight (8) fan speed sensors (8-bit),
52 generated. The interrupts can be masked. In addition, there are over-temp
57 Fan rotation speeds are reported in RPM (rotations per minute) but measured
61 by 1, 2, 4 or 8. Not all RPM values can accurately be represented, so some
63 two pulse per revolution fan is 661 RPM.
69 higher voltages directly. 3.3V, 5V, 12V, -12V and battery voltage all have
70 dedicated inputs. There are several inputs scaled to 0-3V full-scale range
72 a 0-2.5V full-scale range. A 2.5V or 1.82V reference voltage is provided
80 once-only alarms.
