The QUICC32 is always a slave on the IDL bus, with the data clock (DCL) and frame sync
(FSC) signals acting as inputs. As explained in Section C.3, “Data Clock (DCL) and Frame
Sync (FSC) Generation,” this specific application requires the S/T interface be configured
in slave mode on the IDL bus, with external circuitry providing the DCL and FSC signals
to both the QUICC32 and the S/T interface.
The D channel request/grant function is not required for this application since each S/T is
assumed to be directly connected to the NT1 (that is, point-to-point configuration with only
one TE connected to one NT).
The DGNT signal is left unconnected, and DREQ can be directly connected to VSS. As
there is no contention on the D channel, the D channel contention procedure of the
MC145574 should be disabled by setting BR7[6].
Figure C-3 shows the connection between the QUICC32 and a U interface.
