Register 28h, 29h, 2Ah, 2Bh, 2Ch, 2Dh, 2Eh – GPIOx
* Behavior (Power-On Default 00h)
Bit
Name
R/W
Description
0
Direction = 0
R/W
This bit indicates the direction for GPIOx
* pin. When set to 1 GPIOx* will
function as an input, when 0 GPIOx
* will function as an output.
1
Polarity = 0
R/W
This bit indicates the polarity of the GPIOx
* pin. When set to 1 GPIOx* will
be active high, when 0 GPIOx
* will be active low.
2
Bit 2 = 0
R/W
If GPIOx
* is configured as an input, CFAULT will be asserted if GPIOx*
pin is asserted while this bit is set. If GPIO2 is configured as an output, GPIO2
will be asserted if a temperature High limit is exceeded while this bit is set. If
automatic fan speed control is enabled, this bit will be set by default. This can
be used as a SHUTDOWN signal for a catastrophic overtemperature event.
3
Bit 3 = 0
R/W
If GPIOx
* is configured as an input, INT will be asserted if GPIOx* pin is
asserted while this bit is set. If GPIOx
* is configured as an output, GPIOx*
will be asserted if a temperature Low limit is exceeded while this bit is set.
4
Bit 4 = 0
R/W
If GPIOx
* is configured as an input, Fans will go to Alarm Speed if GPIOx*
pin is asserted while this bit is set. If GPIOx
* is configured as an output,
GPIOx
* will be asserted if a Fan Tach limit is exceeded while this bit is set.
5
Bit 5 = 0
R/W
If GPIOx
* is configured as an input, Fans will go to Hot-Plug Speed if
GPIOx
* pin is asserted while this bit is set. If GPIOx* is configured as an
output, GPIOx
* will be asserted if a Fan Fault (Pins 2/23) is detected
while this bit is set.
6
Bit 6 = 0
R
If GPIOx
* is configured as an input, this bit will reflect state of GPIOx* pin.
R/W
If GPIOx
* is configured as an output, GPIOx will be asserted if an AIN high
limit is exceeded while this bit is set.
7
Bit 7 = 0
R/W
If GPIOx
* is configured as an input, this bit will latch a GPIOx* assertion
event. This bit is cleared by writing a 0 to it. If GPIOx
* is configured as an
output, GPIOx
* will be asserted if an AIN Low limit is exceeded while this
bit is set.
*“x” denotes the number of the GPIO pin. Register 28h controls GPIO0, 29h controls GPIO1, etc.
Register 38h, 39h, 3Ah, 3Bh, 3Ch, 3Dh, 3Eh – GPIOx
* Event Mask (Power-On Default 00h)
Bit
Name
R/W
Description
0
Fan 1 = 0
R/W
If GPIOx
* is asserted such that fans should be driven at Alarm or Hot-Plug
Speed, Fan 1 will be set to this speed when this bit is set.
1
Fan 2 = 0
R/W
If GPIOx
* is asserted such that fans should be driven at Alarm or Hot-Plug
Speed, Fan 2 will be set to this speed when this bit is set.
