Description
When this bit is set the ADM1026 monitors all voltage, temperature and fan channels in a round
robin manner.
When this bit is set, the INT output pin is enabled.
Setting this bit clears an interrupt from the voltage, temperature or fan speed channels. Because
GPIO interrupts are level triggered, this bit has no effect on interrupts originating from GPIO
channels. This bit is cleared by writing a 0 to it. If in monitoring mode voltages, temperatures and
fan speeds continue to be monitored after writing to this bit to clear an interrupt, so an interrupt
may be set again on the next monitoring cycle.
When this bit is 1, the ADM1026 monitors voltage (A
IN8
and A
IN9
) on Pins 28 and 27, respectively.
When this bit is 0, the ADM1026 monitors a second thermal diode temperature channel, D2, on
these pins. If the second thermal diode channel is not being used, it is recommended that the bit
be set to 1.
When this bit is 1, the THERM pin (Pin 42) is asserted (go low) if any of the THERM limits are
exceeded. If THERM is pulled low as an input, the DAC and PWM outputs are forced to full scale
until THERM is taken high.
When this bit is 1, the DAC output is enabled for automatic fan speed control (AFC) based on
temperature. When this bit is 0, the DAC Output reflects the value in Reg 04h, the DAC Control
Register.
When this bit is 1, the PWM output is enabled for automatic fan speed control (AFC) based on
temperature. When this bit is 0, the PWM Output reflects the value in Reg 05h, the PWM Control
Register.
Writing a 1 to this bit restores all registers to the power-on defaults. This bit is cleared by writing a
0 to it. For more info, see the Software Reset Function section.
