96 VID signals from the processor to the VRM. Lastly, there are three (3) PWM
110 A sophisticated control system for the PWM outputs is designed into the
112 three temperature sensors. Each PWM output is individually adjustable and
113 programmable. Once configured, the LM85 will adjust the PWM outputs in
115 This feature can also be disabled for manual control of the PWM's.
130 Both have special circuitry to compensate for PWM interactions with the
152 The ADT7468 has a high-frequency PWM mode, where all PWM outputs are
153 driven by a 22.5 kHz clock. This is a global mode, not per-PWM output,
154 which means that setting any PWM frequency above 11.3 kHz will switch
155 all 3 PWM outputs to a 22.5 kHz frequency. Conversely, setting any PWM
156 frequency below 11.3 kHz will switch all 3 PWM outputs to a frequency
162 determining an optimal configuration for the automatic PWM control.
179 The LM96000 supports additional high frequency PWM modes (22.5 kHz, 24 kHz,
180 25.7 kHz, 27.7 kHz and 30 kHz), which can be configured on a per-PWM basis.
225 PWM Control
228 There are three PWM outputs. The LM85 datasheet suggests that the
229 pwm3 output control both fan3 and fan4. Each PWM can be individually
230 configured and assigned to a zone for its control value. Each PWM can be
