VCC, +5V)
A one indicates a High or Low limit has been exceeded.
(VIN2)
A one indicates a High or Low limit has been exceeded.(VIN3
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.
Reserved
Disable Power OK Function. If this bit set to 1, the
PWR_DN# (Pin 6) will keep logical high no mater what
the pwoer VDD or +3.3V drop to the threshold voltage
(4.0v and 2.6v, respectively).
Reserved
A one 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.
A one enables startup of monitoring operations, a zero
puts the part in standby mode.
