DRP Address Map of the GTP_DUAL
Tile
All attributes are stored as binary values in the DRP table. Some attributes use special
mappings from their UCF/HDL values to their binary values. The mappings for these
values are shown in Table D-1.
For attributes not listed in Table D-1, use the following rules to determine the binary
mapping:
• Attributes with TRUE/FALSE values use “1” to represent TRUE and “0” to represent
FALSE.
• Convert integer values to binary.
