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)
