7.10.23.3 LEARNING ETHERNET ON THE QUICC. The following paragraphs detail the
Ethernet functionality on the QUICC. However, they show the additions made to the stan-
dard SCC functionality to implement Ethernet. Therefore, the reader is encouraged to learn
the basics of the SCCs and the overall architecture of the CPM before attempting to learn
this section in great detail.
A first-time user of the QUICC who plans to use Ethernet on the QUICC should first read the
following sections of this user manual.
1. 7.1 RISC Controller, 7.2 Command Set, and 7.3 Dual-Port RAM. The RISC controller
is used to issue special commands to the Ethernet channel. The dual-port RAM is
used to load Ethernet parameters and initialize BDs for use by the Ethernet channel.
2. 7.7 SDMA Channels discusses how SDMA channels are used to transfer data to/from
the Ethernet channel and system memory.
3. 7.8.9 NMSI Configuration explains how clocks are routed to the SCCs through the
bank of clocks.
4. 7.10.1 SCC Overview contains more detailed information on the SCCs that are appli-
