full scale or C0h.
The Voltage Reading registers are updated automatically by the LM96000 at a minimum frequency of 4 Hz. These registers are
read only — a write to these registers has no effect.

The Temperature Reading registers reflect the current temperatures of the internal and remote diodes. Processor (Zone1) Temp
register reports the temperature measured by the thermal diode connected to the Remote1 and Remote1+ pins, Remote
(Zone3) Temp register reports the temperature measured by the thermal diode connected to the the Remote2 and Remote2+
pins, and the Internal (Zone2) Temp register reports the temperature measured by the internal (junction) temperature sensor.
Temperatures are represented as 8 bit, 2’s complement, signed numbers, in Celsius, as shown below in
Table 1
. The Temperature
Reading register will return a value of 80h if the remote diode pins are not used by the board designer or are not functioning
properly. This reading will cause the zone limit bit(s) (bits 6 and 4) in the Interrupt Status Register (41h) and the remote diode fault
status bit(s) (bit 6 or 7) in the Interrupt Status Register 2 (42h) to be set. The Temperature Reading registers are updated
automatically by the LM96000 at a minimum frequency of 4 Hz. These registers are read only — a write to these registers has
no effect.
