A one indicates a High or Low limit has been exceeded.
A one indicates that a Low has been detected on the INT_IN.
A one indicates a High or Low limit has been exceeded. Only “One-Time Interrupt” and
“Default Interrupt” modes are supported (see Sections 8.2 and 8.2). The mode is set by bit-6
of the Interrupt Mask Register 2 (address 04h).
A one indicates that an interrupt has occurred from the Board Temperature Interrupt (BTI)
input pin. BTI can be tied to the OS output of multiple LM75 chips.
A one indicates that a fan count limit has been exceeded.
A one indicates that a fan count limit has been exceeded.
A one indicates GPI (Chassis Intrusion) has gone high.
A one indicates a High or a Low OS Temperature limit has been exceed. Only “One-Time
Interrupt” and “Default Interrupt” modes are supported (see Sections 8.2 and 9.2). The mode
is set by bit 7 of the Interrupt Mask Register 2.
