These registers reflect the PWM duty cycle driving each fan at any given time. When in automatic fan speed control mode, the ADT7467 reports the PWM duty cycles
through these registers. The PWM duty cycle values vary according to the temperature in automatic fan speed control mode. During fan start-up, these registers
report 0x00. In software mode, the PWM duty cycle outputs can be set to any duty cycle value by writing to these registers.
These registers set the target operating point for each temperature channel when the dynamic T
The fans being controlled are adjusted to maintain temperature about an operating point.
These registers become read-only registers when the Configuration Register 1 lock bit is set to 1. Any subsequent attempts to write to these registers fail.
