Table X. Register 0x41 Interrupt Status Register 1 (Power-On Default = 0x00)
Bit
Name
Read/Write
Description
<0>
2.5 V
Read-Only
A 1 indicates the 2.5 V
high or low limit has been exceeded. This bit is cleared on a read
of the status register only if the error condition has subsided.
<1>
V
CCP
Read-Only
A 1 indicates the V
CCP
high or low limit has been exceeded. This bit is cleared on a read
of the status register only if the error condition has subsided.
<2>
V
CC
Read-Only
A 1 indicates the V
CC
high or low limit has been exceeded. This bit is cleared on a read
of the status register only if the error condition has subsided.
<3>
5 V
Read-Only
A 1 indicates the 5 V high or low limit has been exceeded. This bit is cleared on a read of
the status register only if the error condition has subsided.
<4>
R1T
Read-Only
A 1 indicates the Remote 1 low or high temp limit has been exceeded. This bit is
cleared on a read of the status register only if the error condition has subsided.
<5>
LT
Read-Only
A 1 indicates the local low or high temp limit has been exceeded. This bit is cleared on
a read of the status register only if the error condition has subsided.
<6>
R2T
Read-Only
A 1 indicates the Remote 2 low or high temperature limit has been exceeded. This bit is
cleared on a read of the status register only if the error condition has subsided.
<7>
OOL
Read-Only
A 1 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.
Table XI. Register 0x42 Interrupt Status Register 2 (Power-On Default = 0x00)
Bit
Name
Read/Write
Description
<0>
12 V
Read-Only
A 1 indicates the 12 V high or low limit has been exceeded. This bit is cleared on a read
of the status register only if the error condition has subsided.
<1>
OVT
Read-Only
A 1 indicates that one of the THERM overtemperature limits has been exceeded. This bit
is cleared on a read of the status register when the temperature drops below THERM 4rC
<2>
FAN1
Read-Only
A 1 indicates that Fan 1 has dropped below minimum speed or has stalled. This bit is
NOT set when the PWM 1 output is off.
<3>
FAN2
Read-Only
A 1 indicates that Fan 2 has dropped below minimum speed or has stalled. This bit is
NOT set when the PWM 2 output is off.
<4>
FAN3
Read-Only
A 1 indicates that Fan 3 has dropped below minimum speed or has stalled. This bit is
NOT set when the PWM 3 output is off.
<5>
FAN4
Read-Only
A 1 indicates that Fan 4 has dropped below minimum speed or has stalled. This bit is
NOT set when the PWM 3 output is off.
<6>
D1
Read-Only
A 1 indicates either an open or short circuit on the Thermal Diode 1 inputs.
<7>
D2
Read-Only
A 1 indicates either an open or short circuit on the Thermal Diode 2 inputs.
