EPIC®-1 Interface

Pin No. Symbol Input (I) Function

Output (O)

29

DU0/SIP4 I/IO (OD) Data Upstream Input; IOM- or PCM-configuration.

30

DU1/SIP5 I/IO (OD) Serial Interface Port, SLD-configuration.

32

DU2/SIP6 I/IO (OD) Depending on the bit OMDR:COS these lines

33

DU3/SIP7 I/IO (OD) have push pull or open drain characteristic.

For unassigned channels or when bit

OMDR:CSB is reset the pins are in the state

high impedance.

34

DD0/SIP0 O/IO (OD) Data Downstream Output, IOM- or PCM-

35

DD1/SIP1 O/IO (OD) configuration.

36

DD2/SIP2 O/IO (OD) Serial Interface Port, SLD-configuration.

37

DD3/SIP3 O/IO (OD) Depending on the bit OMDR:COS these lines

have push pull or open drain characteristic.

For unassigned channels or when bit

OMDR:CSB is reset the pins are in the state

high impedance.
