2.1.1.5 XOR Gate

To get a HIGH(1) output from an XOR gate, the number of HIGH(1) inputs must be odd. Looking at the truth table, TRUTH[1], TRUTH[2], TRUTH[4], and TRUTH[7] fulfill this requirement. This means that these must be HIGH(1) and the rest must be LOW(0), giving the hex value 0x96 to put into the TRUTHn register.
