TDM Bus Configurations
Switched Mode
In this mode, PA(7) = SWMODE_N = 0 and PA(0) = COMCLK_N = 1.
In switched mode, the QuadFALC multiplexed TDM bus is tied to the first TDM bus on
P4. The second TDM bus on P4 is tied to the MPC8260. The TDM busses clock and frame
synchronization signals are provided by connector P4. In NT mode, the QuadFALC can
synchronize on an external network reference clock provided on P4.
