The filter curves were purposely offset for clarity.Figure 12 shows the filter in use in a typical Intel processor on a

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.

TEMPERATURE DATA FORMAT

Temperature data can only be read from the Local and Remote Temperature value registers. The data format for

all temperature values is left justified 16-bit word available in two 8-bit registers. Unused bits will always report

"0". All temperature data is clamped and will not roll over when a temperature exceeds full-scale value.

Remote temperature data for all channels can be represented by an 11-bit, two's complement word or unsigned

binary word with an LSb (Least Significant Bit) equal to 0.125°C.
