MC68302 Applications
The other three physical interfaces, PCM highway, IDL, and GCI, are called multiplexed in-
terfaces since they allow data from one, two, or all three SCCs to be time multiplexed to-
gether on the same pins. If a multiplexed interface is chosen, the first SCC to use that
interface must be SCC1, since the three multiplexed modes share pins with SCC1 (see Fig-
ure D-22). After choosing a multiplexed mode, you can decide independently whether SCC2
and SCC3 should be part of the multiplexed interface or whether they should have their own
set of NMSI pins.
If you are working in ISDN, transparent mode can be quite useful in sending and receiving
transparent data over the 2B + D interface. IDL and GCI allow the SCCs to transmit and re-
ceive data on the two 64 kbps B channels and on the one 16 kbps D channel in basic rate
ISDN. If you are not interfacing to a 2B + D ISDN environment, you can probably rule out
using IDL and GCI.
