1RO
Reserved for Local Temperature Data Readout. Will always read "0".
EF (Error Flag) for Remote Temperature Data Readout. This bit indicates that an error was detected
during the measurement of the current remote Temperature sensor such as a diode fault condition. When a
diode fault occurs the value of the temperature reading will be 200h or -256C.
0: No error detected.
1: Error detected.
2RO
SNUM (Sensor Number). This field indicates the number of the current Temperature Sensor, to which the
data in the Temperature Readout field belongs. Temperature Sensor 0 is always assigned to the local
sensor of the LM41.
0: Local temperature sensor (see Table Thermal Diode Input Mapping)
1: Remote sensor (see Table Thermal Diode Input Mapping)

All LM41 temperature data has a common format. The LM41’s temperature data format is two’s complement and has 10-bits of
resolution with the LSb having a weight of 0.5 C. The LM41 can resolve temperature between +255.5 C and -256 C, inclusive.
It can measure local temperatures between +85 C and 0 C and remote temperatures between +125 C and 0 C with an
accuracy of ±3.0 C.
