• V — Compare high or low, not midband; store results from capture functionality if
configured.
• D — Drive data from source functionality if configured.
• M — Compare midband, not high or low.
Note Termination mode settings affect the termination applied to all non-driving
pin states. Non-drive states include L, H, M, V, X and potentially -. Refer to the
Programmable input termination mode specification for more information.
