These voltage readings are in twos complement format.
If the extended resolution bits of these readings are also being read, the Extended Resolution registers (Reg. 0x76, 0x77) should be read first. Once the Extended
Resolution registers get read, the associated MSB reading registers get frozen until read. Both the Extended Resolution Registers and the MSB registers get frozen.

These temperature readings are in twos complement format.
*Note that a reading of 0x80 in a temperature reading register indicates a diode fault (open or short) on that channel. If the extended resolution bits of these readings are
also being read, the Extended Resolution registers (Reg. 0x76, 0x77) should be read first. Once the Extended Resolution registers get read, all associated MSB reading
registers get frozen until read. Both the Extended Resolution Registers and the MSB registers get frozen.

These registers count the number of 11.11
μ
s periods (based on an internal 90 kHz clock) that occur between a number of consecutive fan TACH pulses (default = 2).
The number of TACH pulses used to count can be changed using the Fan Pulses Per Revolution Register (Reg. 0x7B). This allows the fan speed to be accurately
measured. Since a valid Fan Tachometer reading requires that two bytes are read, the low byte MUST be read first. Both the low and high bytes are then frozen until
read. At power-on, these registers contain 0x0000 until such time as the first valid fan TACH measurement is read in to these registers. This prevents false interrupts
from occurring while the fans are spinning up.
A count of 0xFFFF indicates that a fan is:
1. Stalled or Blocked
(object jamming the fan)
2. Failed
(internal circuitry destroyed)
3. Not Populated
(The ADT7460 expects to see a fan connected to each TACH.
If a fan is not connected to that TACH, its TACH minimum high and low byte
should be set to 0xFFFF.)
4. Alternate Function
, e.g., TACH4 reconfigured as
THERM
pin
5. 2-Wire Instead of 3-Wire Fan
