— Chapter 16, “CPM Multiplexing,” describes the CPM multiplexing logic (CMX) that connects

the physical layer—UTOPIA, MII, modem lines.

— Chapter 17, “Baud-Rate Generators (BRGs),” describes the eight independent, identical

baud-rate generators (BRGs) that can be used with the FCCs, SCCs, and SMCs.

— Chapter 18, “Timers,” describes the timer implementation, which can be configured as four

identical 16-bit or two 32-bit general-purpose timers.

— Chapter 19, “SDMA Channels and IDMA Emulation,” describes the two physical serial DMA

(SDMA) channels on the MPC8280.

— Chapter 20, “Serial Communications Controllers (SCCs),” describes the four 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 21, “SCC UART Mode,” describes the MPC8280 implementation of universal

asynchronous receiver transmitter (UART) protocol that sends low-speed data between

devices.

— Chapter 22, “SCC HDLC Mode,” describes the MPC8280 implementation of HDLC protocol.

— Chapter 23, “SCC BISYNC Mode,” describes the MPC8280 implementation of byte-oriented

BISYNC protocol developed by IBM for use in networking products.

— Chapter 24, “SCC Transparent Mode,” describes the MPC8280 implementation of transparent

mode (also called totally transparent mode), which provides a clear channel on which the SCC

can send or receive serial data without bit-level manipulation.

— Chapter 25, “SCC Ethernet Mode,” describes the MPC8280 implementation of Ethernet

protocol.

— Chapter 26, “SCC AppleTalk Mode,” describes the MPC8280 implementation of AppleTalk.

— Chapter 27, “Universal Serial Bus Controller,” describes the MPC8280’s USB controller,

including basic operation, the parameter RAM, and registers.

— Chapter 28, “Serial Management Controllers (SMCs),” describes two serial management

controllers, full-duplex ports that can be configured independently to support one of three

protocols—UART, transparent, or general-circuit interface (GCI).

— Chapter 29, “Multi-Channel Controllers (MCCs),” describes the MPC8280’s multi-channel

controller (MCC), which handles up to 128 serial, full-duplex data channels.

— Chapter 30, “Fast Communications Controllers (FCCs),” describes the MPC8280’s fast

communications controllers (FCCs), which are SCCs optimized for synchronous high-rate

protocols.

— Chapter 31, “ATM Controller and AAL0, AAL1, and AAL5,” describes the MPC8280 ATM

controller, which provides the ATM and AAL layers of the ATM protocol. The ATM controller

performs segmentation and reassembly (SAR) functions of AAL5, AAL1, and AAL0, and

most of the common parts convergence sublayer (CP-CS) of these protocols.

— Chapter 32, “ATM AAL1 Circuit Emulation Service,” describes the implementation of circuit

emulation service (CES) using ATM adaptation layer type 1 (AAL1) on the MPC8280.
