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 = 90C = 5Ah
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.
