XOR Tree Test

The aSC7621 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

included in the test tree. Connections to the XOR tree are shown in Figure 12.

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.
