This register specifies the minimum duty cycle that the PWM will output when the measured temperature reaches the
Temperature LIMIT register setting.
This register becomes Read-only when the Ready/Lock/Start/Override register Lock bit is set. Any further attempts to write
to this register shall have no effect. After power up the default value is used whenever the Ready/Lock/Start/Override
register Start bit is cleared even though modifications to this register are possible.

These are the temperature limits for the individual zones. When the current temperature equals this limit, the fan will be
turned on if it is not already. When the temperature exceeds this limit, the fan speed will be increased according to the
algorithm set forth in the Auto Fan Range, PWM Frequency register description, Default = 90
