In the Auto Fan mode, if a zone exceeds the temperature set in the Absolute Temperature Limit register, all of the PWM outputs
will incresase its duty cycle to 100%. This is a safety feature that attempts to cool the system if there is a potentially catastrophic
thermal event. If set to 80h (-128C), the feature is disabled. Default=100C=64h
These registers become Read Only when the Ready/Lock/Start/Override register Lock bit is set. Any further attempts to write to
these registers shall have no effect. After power up the default values are used whenever the Ready/Lock/Start/Override register
Start bit is cleared even though modifications to these registers are possible.
