Allocation Table

The label of a synchronous connection can be distributed over several bytes in the Allocation Table.

Each byte in mTableData contains a value that specifies the identification number of the label it belongs to. If the device is a timing master, the MSB of the byte value is used to indicate if the label is in use or not, otherwise the MSB should be ignored. The label number thus can be determined by byte value & 0x7F. If the resulting label number is 0x70, the byte is not used for any label.
