All Z
To apply vectors to XOR chains on a system board, other chips on the board must be tri-stated to allow
for this vector application. This is a feature that enables all GMCH outputs to be tristated when the I/O
Controller Hub is in the XOR chain mode. This mode can also be activate using the assigned reset strap.
Tri-state GMCH Outputs
When testing other devices in the system, the GMCH outputs can be tri-stated. To tri-state these outputs
pull the SMAA10 pin low (GND) prior to deasserting RESET#. The following sequence will put the
GMCH into tri-state mode:
1. 1. Deassert RESET# high and SMAA10 low
2. 2. Assert RESET# low; maintain SMAA10 low
3. 3. Deassert RESET# high; maintain SMAA10 low
4. 4. RESET# must be maintained high for the duration of testing.
No external clocking of the GMCH is required.
