INITIALIZATION
Bit 7: A one restores power on default value to all registers except the Serial Bus Address register.
This bit clears itself since the power on default is zero.
Bit 6: The logical 1 in this bit drives a zero on BEEP/GPO# pin.
Bit 5: Reserved
Bit 4: Reserved
Bit 3: A one disables the SMI# output without affecting the contents of Interrupt Status Registers.
The device will stop monitoring. It will resume upon clearing of this bit.
Bit 2: Reserved
Bit 1: A one enables the SMI# Interrupt output.
Bit 0: A one enables startup of monitoring operations, a zero 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.
