FMTJ
ForMaT Justify
Class Format memory management
Description Corrects some types of timing errors for the current data in the format buffer. The following
errors are corrected:
• Pixel Rate errors 2071 and 2072
• Video Memory Size error 2550
• Horizontal Blanking errors 2140, 2141, 2150 and 2155
• Horizontal Total errors 2090 and 2091
• Horizontal Sync Pulse Width errors 2181 and 2201
The justification routine tries to keep the format close to your original specifications.
However, the format should be reviewed after it is justified to make sure it still meets your
timing requirements.
