Part V
Communications Processor Module
Intended Audience
This part is intended for system designers who need to implement various communications protocols on
the MPC885. It assumes a basic understanding of the PowerPC exception model, the MPC885 interrupt
structure, as well as a working knowledge of the communications protocols to be used. A complete
discussion of these protocols is beyond the scope of this book.
Contents
This part describes behavior of the MPC885 communications processor module (CPM) and the RISC
communications processor (CP) that it contains (note that this is separate from the embedded MPC8xx
processor). It contains the following chapters:
•
Chapter 17, “Communications Processor Module and CPM Timers,”
provides a brief overview of
the MPC885 CPM and a detailed discussion of the clocking mechanisms supported.
•
Chapter 18, “Communications Processor,”
describes the RISC communications processor (CP),
which handles the low-level communications tasks, freeing the core for higher-level tasks.
•
Chapter 19, “SDMA Channels and IDMA Emulation,”
describes the two physical serial DMA
(SDMA) channels on the MPC885 with which the CP implements virtual SDMA channels.
•
Chapter 20, “Serial Interface,”
describes the serial interface (SI) in which the physical interface to
all SCCs and SMCs is implemented.
•
Chapter 21, “Serial Communications Controllers,”
describes the serial communications controllers
(SCC), which can be configured independently to implement different protocols for bridging
functions, routers, and gateways, and to interface with a wide variety of standard WANs, LANs,
and proprietary networks.
•
Chapter 22, “SCC UART Mode,”
describes the MPC885 implementation of universal
asynchronous receiver transmitter (UART) protocol, used for sending low-speed data between
devices.
•
Chapter 23, “SCC HDLC Mode,”
describes the MPC885 implementation of HDLC protocol.
•
Chapter 24, “SCC AppleTalk Mode,”
describes the MPC885 implementation of AppleTalk, a set
of protocols developed by Apple Computer, Inc. to provide a LAN service between Macintosh
computers and printers.
•
Chapter 25, “SCC Asynchronous HDLC Mode and IrDA,”
describes the asynchronous HDLC and
IrDA use of HDLC framing techniques with UART-type characters.
•
Chapter 26, “SCC BISYNC Mode,”
describes the MPC885 implementation of byte-oriented
BISYNC protocol developed by IBM for use in networking products.
