Table XII. Register 0x40 – Configuration Register 1 (Power-On Default = 0x00)
Bit
<0>
Name
STRT
R/W
Read/Write
Description
Logic 1 enables monitoring and PWM control outputs based on the limit settings pro-
grammed. Logic 0 disables monitoring and PWM control based on the default power-up
limit settings. Note that the limit values programmed are preserved even if a logic 0 is
written to this bit and the default settings are enabled. This bit becomes read-only and
cannot be changed once Bit 1 (LOCK bit) has been written. All limit registers should be
programmed by BIOS before setting this bit to 1. (Lockable.)
Logic 1 locks all limit values to their current settings. Once this bit is set, all lockable
registers become read-only and cannot be modified until the ADT7460 is powered down
and powered up again. This prevents rogue programs such as viruses from modifying
critical system limit settings. (Lockable.)
This bit gets set to 1 by the ADT7460 to indicate that the device is fully powered-up
and ready to begin systems monitoring.
When set to 1, this runs all fans at full speed. Power-on default = 0. This bit does not
get locked at any time.
Read Only and Reserved for Future Use
Logic 1 disables fan spin-up for two TACH pulses. Instead, the PWM outputs will go
high for the entire fan spin-up timeout selected.
When this bit is set to 1, the SMBus timeout feature is disabled. This allows the
ADT7460 to be used with SMBus controllers that cannot handle SMBus
timeouts. (Lockable.)
When this bit is set to 1, the ADT7460 rescales its V
CC
pin to measure a 5 V supply. If
this bit is 0, the ADT7460 measures V
CC
as a 3.3 V supply. (Lockable.)

Table XIII. Register 0x41 – Interrupt Status Register 1 (Power-On Default = 0x00)
Bit
<0>
Name
2.5V
R/W
Read Only
Description
A one indicates the 2.5 V
High or Low limit has been exceeded. This bit gets cleared on
a read of the Status Register only if the error condition has subsided.
Reserved for future use
A one indicates the V
CC
High or Low limit has been exceeded. This bit gets cleared on a
read of the Status Register only if the error condition has subsided.
Reserved for future use
A one indicates the Remote 1 Low or High Temp limit has been exceeded. This bit gets
cleared on a read of the Status Register only if the error condition has subsided.
A one indicates the Local Low or High Temp limit has been exceeded. This bit gets
cleared on a read of the Status Register only if the error condition has subsided.
A one indicates the Remote 2 Low or High Temp limit has been exceeded. This bit gets
cleared on a read of the Status Register only if the error condition has subsided.
A one indicates that an Out-of-Limit event has been latched in Status Register 2. This
bit is a logical OR of all status bits in Status Register 2. Software can test this bit in
isolation to determine whether any of the voltage, temperature, or fan speed readings
represented by Status Register 2 are out-of-limit. This saves the need to read Status
Register 2 every interrupt or polling cycle.
