TDM Bus Configurations
In this mode, PA(7) = SWMODE_N = 1 and PA(0) = COMCLK_N = 1.
In multiplex direct mode, the four framers have the same rhythm. The QuadFALC system interface is in multiplex mode; the first QuadFALC TDM bus is directly tied to the CPM TDM bus TDMa1. The TDM bus clock and the frame synchronization signal are provided by the QuadFALC. In NT mode, the QuadFALC can synchronize on an external network reference clock provided on connector P4.
