18 The ADT7470 uses the 2-wire interface compatible with the SMBus 2.0
20 external temperatures. It has four (4) 16-bit counters for measuring fan speed.
21 There are four (4) PWM outputs that can be used to control fan speed.
23 A sophisticated control system for the PWM outputs is designed into the ADT7470
25 temperature sensors. Each PWM output is individually adjustable and
26 programmable. Once configured, the ADT7470 will adjust the PWM outputs in
28 feature can also be disabled for manual control of the PWM's.

59 point1: Set the pwm speed at a lower temperature bound.
60 point2: Set the pwm speed at a higher temperature bound.
62 The ADT7470 will scale the pwm between the lower and higher pwm speed when
63 the temperature is between the two temperature boundaries. PWM values range
