45 16 general purpose digital I/O lines, eight (8) fan speed sensors (8-bit),

57 Fan rotation speeds are reported in RPM (rotations per minute) but measured
58 in counts of a 22.5kHz internal clock. Each fan has a high limit which
59 corresponds to a minimum fan speed. If the limit is exceeded, an interrupt
60 can be generated. Each fan can be programmed to divide the reference clock

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

83 times a second. Fan speed measurement time depends on fan speed and
84 divisor. It can take as long as 1.5 seconds to measure all fan speeds.
86 The ADM1026 has the ability to automatically control fan speed based on the
88 used to control fan speed. Usually only one of these two outputs will be
94 controlling fan speed with the PWM and DAC outputs. The fan speed sensors
95 do not have PWM compensation, so it is probably best to control the fan
99 GPIO lines. Unfortunately, the chip may not be connected to the VID lines
