Ñ Chapter 13, ÒCommunications Processor Module Overview,Ó provides a brief
overview of the MPC8260 CPM.
Ñ Chapter 14, ÒSerial Interface with Time-Slot Assigner,Ó describes the SIU, which
controls system start-up, initialization and operation, protection, as well as the
external system bus.
Ñ Chapter 15, ÒCPM Multiplexing,Ó describes the CPM multiplexing logic (CMX)
which connects the physical layerÑUTOPIA, MII, modem lines,
Ñ Chapter 16, ÒBaud-Rate Generators (BRGs),Ó describes the eight independent,
identical baud-rate generators (BRGs) that can be used with the FCCs, SCCs,
and SMCs.
Ñ Chapter 17, ÒTimers,Ó describes the MPC8260 timer implementation, which can
be conÞgured as four identical 16-bit or two 32-bit general-purpose timers.
Ñ Chapter 18, ÒSDMA Channels and IDMA Emulation,Ó describes the two
physical serial DMA (SDMA) channels on the MPC8260.
Ñ Chapter 19, ÒSerial Communications Controllers (SCCs),Ó describes the four
serial communications controllers (SCC), which can be conÞgured
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.
Ñ Chapter 20, ÒSCC UART Mode,Ó describes the MPC8260 implementation of
universal asynchronous receiver transmitter (UART) protocol that is used for
sending low-speed data between devices.
Ñ Chapter 21, ÒSCC HDLC Mode,Ó describes the MPC8260 implementation of
HDLC protocol.
Ñ Chapter 22, ÒSCC BISYNC Mode,Ó describes the MPC8260 implementation of
byte-oriented BISYNC protocol developed by IBM for use in networking
products.
Ñ Chapter 23, ÒSCC Transparent Mode,Ó describes the MPC8260 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.
Ñ Chapter 24, ÒSCC Ethernet Mode,Ó describes the MPC8260 implementation of
Ethernet protocol.
Ñ Chapter 25, ÒSCC AppleTalk Mode,Ó describes the MPC8260 implementation of
AppleTalk.
Ñ Chapter 26, ÒSerial Management Controllers (SMCs),Ó describes two serial
management controllers, full-duplex ports that can be conÞgured independently
to support one of three protocolsÑUART, transparent, or general-circuit
interface (GCI).
