As with the S/T interface example, the U interface must be configured in slave mode with
the DCL and FSC signals provided to both the QUICC32 and the U interface.
In slave mode, the FSX and FSR signals of the MC145572 must be connected together.
There are no DREQ/DGRANT signals on the U interface.
C.3 Data Clock (DCL) and Frame Sync (FSC)
The main consideration when connecting multiple interfaces to the same physical medium
is the clock and frame sync generation.
As stated earlier, the QUICC32 does not provide DCL and FSC signals. The U or S/T
interface could be configured in master mode on the IDL bus and generate both DCL and
FSC synchronized to the line-interface signal.
To have all the B- and D channels of a multi-interface system synchronized on the same
TDM bus, only one S/T or U interface should be configured as master to provide common
DCL and FSC signals to the QUICC32 and all other interfaces.
