aSC7611
XOR Tree Test
The aSC7611 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.
This register becomes Read-Only when the Ready/Lock/Start/Override register Lock bit is set. Any further attempts to write
to this registers shall have no effect.
Register 70-7Fh: Vendor Specific Registers
These registers are for vendor specific features, including test registers. They will not default to a specific value on power
up.
