5.7.1.3 XOR Chain Test Pattern Consideration for Differential Pairs
Below are the differential signals in the XOR chains that must be treated as pairs. Pin1 and Pin2 as
shown below must always be complementary to each other. For example, if a 1 is driven on ADSTB0, a
0 must be driven on ADSTB0# and vice versa. This will need to be considered when applying test
patterns to these chains.
