Figure 3
shows the filter in use in a typical Intel processor on
a 45/65/90 nm process system. Note that the two curves have
been purposely offset for clarity. Inserting the filter does not
induce an offset as shown.

curves were purposely offset for clarity.
1.5 TEMPERATURE DATA FORMAT
Temperature data can only be read from the Local and Re-
mote Temperature registers.
Remote temperature data with the digital filter off is repre-
sented by an 10-bit plus sign, two's complement word and 11-
bit unsigned binary word with an LSb (Least Significant Bit)
equal to 0.125°C. The data format is a left justified 16-bit word
available in two 8-bit registers. Unused bits report "0".
Remote temperature data with the digital filter on is repre-
sented by a 12-bit plus sign, two's complement word and 13-
bit unsigned binary word with an LSb (Least Significant Bit)
equal to 0.03125°C (1/32°C). The data format is a left justified
16-bit word available in two 8-bit registers. Unused bits report
"0".

Local Temperature data is represented by a 10-bit plus sign,
two's complement word with an LSb (Least Significant Bit)
equal to 0.125°C. The data format is a left justified 16-bit word
available in two 8-bit registers. Unused bits will always report
"0". Local temperature readings greater than +127.875°C are
clamped to +127.875°C, they will not roll-over to negative
temperature readings.
