Allocation Table data
The data layout tableData depends on bit 0 of eventModeFlags.
If bit 0 of eventModeFlags is clear tableData contains length/4 records with the following fields. (Other data layouts are not specified yet.)
- Bit 0..12 (LabelIdent): Synchronous Connection Label
- Bit 12..15 (LabelStatus):
- •
- 0: label unchanged
- •
- 4: label has been added (allocated)
- •
- 8: label has been removed (de-allocated) List removed labels at the end of the table! Listing of removed labels is optional.
- •
- Bit 16..31 (LabelWidth): Width of the label in bytes
Data layout: if((eventModeFlags & 0x0001) == 0) layout A: SLLLWWWWSLLLWWWWSLLLWWWW... if((eventModeFlags & 0x0001) == 0x0001) layout B: SLLLWWWW< channels >SLLLWWWW< channels >SLLLWWWW< channels >...
- •
- S: status flags
- •
- 0x4: 1: new label (alloc)
- •
- 0x8: 1: this label has been removed (dealloc)
- LLL: label number
- WWWW: label width
- < channels >: list of 16-bit channel numbers (size = label width)
