Logic 1 enables start-up of ADM1024, logic 0 places it in standby mode. Caution: The outputs of
the interrupt pins will not be cleared if the user writes a zero to this location after an interrupt has
occurred (see “
INT
Clear” bit). At start-up, limit checking functions and scanning begins. Note, all
high and low limits should be set into the ADM1024 prior to turning on this bit. (Power-Up Default = 0)
Logic 1 enables the
INT
_output. 1 = Enabled 0 = Disabled (Power-Up Default = 0).
0 =
THERM
disabled.
1 =
THERM
enabled.
During Interrupt Service Routine (ISR) this bit is asserted Logic 1 to clear INT output without
affecting the contents of the Interrupt Status Register. The device will stop monitoring. It will resume
upon clearing of this bit. (Power-Up Default = 0)
Setting this bit generates a low-going 45 ms reset pulse at Pin 12. This bit is self-clearing and power-
up default is 0.
Default = 0.
A one clears the
THERM
output without changing the Status Register contents.
Logic 1 restores Power-Up default values to the Configuration register, Interrupt status registers,
Interrupt Mask Registers, Fan Divisor Register, and the Temperature Configuration Register. This bit
automatically clears itself since the power-on default is zero.

NOTES
1. Any time the STATUS Register is read out, the conditions (i.e., Register) that are read are automatically reset. In the case of the channel priority indication, if two
or more channels were out of limits, then another indication would automatically be generated if it was not handled during the ISR.
2. In the Mask Register, the errant voltage interrupt may be disabled, until the operator has time to clear the errant condition or set the limit higher/lower.
