Name
Least Significant Byte of the Signed Remote Diode Temperature Reading
This is the LSB of the 2’s complement value, representing the temperature of
the remote diode connected to the LM96163. RT4 has a weight 0.5°C, RT3 has
a weight of 0.25°C, and RT2 has a weight of 0.125°C. If the digital filter is turned
off RT1:RT0 have a value of 00 unless extended resolution (Reg 45h STFBE
bit set) is enabled. If extended resolution is chosen, for readings greater than
127.875 RT1:RT0=11 and for other cases RT1:RT0=00. When the digital filter
is turned on and extended resolution enabled: RT1 has a weight of 0.0625 and
RT0 has a weight of 0.03125°C
These bits are unused and always read as 0.
Most Significant Byte of the Unsigned Format Remote Diode Temperature
Reading
The most significant 8-bits of the unsigned format value, representing the
temperature of the remote diode connected to the LM96163. Bit 7 has a weight
of 128°C, bit 6 has a weight of 64°C, and bit 0 has a weight of 1°C. This byte to
be read before the LSB.
Least Significant Byte of the Unsigned Format Remote Diode Temperature
Reading
This is the LSB of the unsigned value, representing the temperature of the
remote diode connected to the LM96163. Bit 4 has a weight 0.5°C, bit 3 has a
weight of 0.25°C, and bit 2 has a weight of 0.125°C. if the digital filter is turned
off RUT1:RUT0 have a value of 00. When the digital filter is turned on: bit 1 has
a weight of 0.0625 and bit 0 has a weight of 0.03125°C
These bits are unused and always read as 0.
Remote Temperature Offset (MSB and LSB)
These registers contain the value added to or subtracted from the remote
diode’s reading to compensate for the different non-ideality factors of different
processors, diodes, etc. The 2’s complement value, in these registers is added
to the output of the LM96163’s ADC to form the temperature reading contained
in registers 01 and 10. These registers have the same format as the MSB and
LSB Remote Diode Temperature Reading registers with the digital filter off.
These bits are not used and always read as 0.
Remote HIGH Setpoint (MSB and LSB)
High setpoint temperature for remote diode. Same format as Unsigned
Remote Temperature Reading (registers 31 and 32) or Signed Remote
Temperature Reading (registers 01 and 10) with the digital filter off. Is it
programmable by the USF bit found in the Enhanced configuration Register.
These bits are not used and always read as 0.
Remote LOW Setpoint (MSB and LSB)
Low setpoint temperature for remote diode. Same format as Signed Remote
Temperature Reading (registers 01 and 10) with the digital filter off.
These bits are not used and always read as 0.
