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.

 show the specific implementation of this mode. 

Grey lines indicate unused connections.
