37 16 general purpose digital I/O lines, eight (8) fan speed sensors (8-bit),
50 in counts of a 22.5kHz internal clock. Each fan has a high limit which
51 corresponds to a minimum fan speed. If the limit is exceeded, an interrupt
52 can be generated. Each fan can be programmed to divide the reference clock

75 times a second. Fan speed measurement time depends on fan speed and
76 divisor. It can take as long as 1.5 seconds to measure all fan speeds.
78 The ADM1026 has the ability to automatically control fan speed based on the
80 used to control fan speed. Usually only one of these two outputs will be
86 controlling fan speed with the PWM and DAC outputs. The fan speed sensors
87 do not have PWM compensation, so it is probably best to control the fan
