Figure 11 describes the filter output in response to a step input and an impulse input.
a) Seventeen and fifty degree step b) Impulse response with input c) Impulse response with input
response transients less than 4°C transients great than 4°C

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.
