Rate-matching allows the user to configure TSI device in such a way that all input streams operate in the same rate while output streams operate in different rates. This feature apparently enhances the flexibility of device's TDM interfaces. TSI devices supporting rate-matching can be configured to work in either “regular mode” (input and output streams operate in the same rate) or “Mux/Deux mode” in which rate-matching is possible. Four control bits (DR[3:0]) in Control Register configure different rate combinations, as shown in the following chart. Refer to application note AN-852 for more details.
