1.5 QUICC SERIAL CONFIGURATIONS

The QUICC offers an extremely flexible set of communications capabilities. Although a full

understanding of the possibilities requires reading the appropriate sections, some of the

possibilities are shown in the following diagrams. They show possible connections between

QUICC devices. In addition, connections are often shown between QUICCs and the

MC68302 to show the compatibility between these devices.

For readability, transceivers are usually omitted in the following diagrams. For local on-

board communications, however, transceivers are often optional and depend on the proto-

col used.

Figure 1-4 shows the Ethernet LAN capability of the QUICC. An external SIA transceiver is

required to complete the interface to the media. This functionality is implemented in the

MC68160 enhanced Ethernet serial transceiver (EEST

™). The MC68160 EEST supports
