The following table shows the table of parameters holding the LDPC circulants for a base matrix.
| Bit | Access Type | Description | ||
|---|---|---|---|---|
| 18:18 | R/W | Flag to indicate that operation applies to parity bits (used by encoder) | ||
| 17:17 | R/W | Flag to indicate first use of associated column | ||
| PSIZE > 128 | Bit | PSIZE ≤ 128 (Provided NO_PACKING is 0) | ||
| 16:8 | R/W | Rotation | 16 | Indicates a no-operation when packed. |
| 15 | If encode: last operation in layer.If decode: last circulant in sub-matrix. (only used when SPECIAL_QC is 1) | |||
| 14:8 | Rotation | |||
| 7:0 | R/W | Column of base matrix | ||
