Table 198. XOR Chain #1 (RTCRST# Asserted for 4 PCI Clocks While PWROK Active)
82801EB ICH5 / 82801ER ICH5R Datasheet
It is important to note that the number of inputs pulled to 1 will affect the expected chain output
value. If the number of chain inputs pulled to 1 is even, then expect 1 at the output. If the number of
chain inputs pulled to 1 is odd, expect 0 at the output.
Continuing with the example in
sequence, the XOR Output will toggle between 0 and 1. Any break in the toggling sequence (e.g.,
“1011”) will identify the location of the short or open.
