5.0 XOR TEST MODE
The LM96000 incorporates a XOR tree test mode. When the test mode is enabled by setting the “XEN” bit high
in the Test Register at address 6Fh via the SMBus, the part will enter XOR test mode.
Since the test mode an XOR tree, the order of the signals in the tree is not important. SMBDAT and SMBCLK
are not to be included in the test tree.
