The part incorporates an XOR tree test mode. When the test mode is enabled by setting the ‘XEN’ bit
high via SMBus, the part enters XOR test mode.
The following signals are included in the XOR test tree:
Since the test mode is XOR tree, the order of the signals in the tree is not important. SDA and SCL
are not included in the test tree.
Register 79h: SMSC Test Register
This is a read/write register. Writing this register may produce unwanted results.
This register becomes read only when the Lock bit is set. Any further attempts to write to this register
shall have no effect.
Register 7Ah: SMSC Test Register
This is a read/write register. Writing this register may produce unwanted results.
Register 7Bh: SMSC Test Register
R/W
This is a read/write register. Writing this register may produce unwanted results.
These registers become read only when the Lock bit is set. Any further attempts to write to these
registers shall have no effect.
