PRELIMINARY
Bit 3:The logical 1 disables the SMI# and IRQ outputs without affecting the contents of Interrupt
Status Registers. The device will stop monitoring. It will resume upon clearing of this bit.
Bit 2:The logical 1 enables the IRQ Interrupt output.
Bit 1:The logical 1 enables the SMI# Interrupt output.
Bit 0: 1 enables startup of monitoring operations
0 puts the part in standby mode.
Note: The outputs of Interrupt pins will not be cleared if the user writes a zero to this location after
an interrupt has occurred unlike "INT_CLEAR'' bit.

Bit 7: The logical 1 indicates the fan count limit has been exceeded.
Bit 6: The logical 1 indicates the fan count limit has been exceeded.
