Adds specified CCID, with specified configuration, to a local CC configuration structure on Band which Id = 0.

If there is insufficient capacity for the new CC the function will return an error. Initiates CC update (enable CCUpdate trigger TUSER Single Shot).

The returned CCCfg.Sequence is translated as there is no explicit indication that SEQUENCE[i] is not used - 0 can define the slot as either used or not used. Sequence data that is returned in the CCIDSequence is not the same as what is written in the registers. The translation is:

  • CCIDSequence.CCID[i] = -1 - if [i] is unused slot
  • CCIDSequence.CCID[i] = CCID - if [i] is used slot
  • a returned CCIDSequence->Length = length in register + 1
