DIAGNOSTICS
The sync counter can be used as an input sync and data source in order to perform diagnostics.
The diagnostic outputs are captured in the snapshot RAM and compared with predicted results. The whole
chip except for the I/O pads, the high speed input circuit and the output format circuit can be checked this
way. Section 6.6 tabulates the diagnostic configurations and their expected snapshot outputs.
