The TSA (Time Slot Assigner) purpose is to route some TDM time-slots to other internal serial controllers. It is available in some PowerQUICC SoC such as the MPC885 or MPC866. It is also available on some Quicc Engine SoCs. This current version support CPM1 SoCs only and some enhancement are needed to support Quicc Engine SoCs.
