Freescale Semiconductor

Features

—AppleTalk

— Universal asynchronous receiver transmitter (UART)

— Synchronous UART

— Serial infrared (IrDA)

— Binary synchronous communication (BISYNC)

— Totally transparent (bit streams)

— Totally transparent (frame based with optional cyclic redundancy check (CRC))

•

Up to two serial management channels (SMCs) supporting the following protocols:

— UART (low-speed operation)

— Transparent

— General circuit interface (GCI) controller

— Provide management for BRI devices as GCI controller in time-division multiplexed (TDM)

channels

•

Universal serial bus (USB)—Supports operation as a USB function endpoint, a USB host controller,

or both for testing purposes (loop-back diagnostics)

— USB 2.0 full-/low-speed compatible

— The USB function mode has the following features:

– Four independent endpoints support control, bulk, interrupt, and isochronous data transfers.

– CRC16 generation and checking

– CRC5 checking

– NRZI encoding/decoding with bit stuffing

– 12- or 1.5-Mbps data rate

– Flexible data buffers with multiple buffers per frame

– Automatic retransmission upon transmit error

— The USB host controller has the following features:

– Supports control, bulk, interrupt, and isochronous data transfers

– CRC16 generation and checking

– NRZI encoding/decoding with bit stuffing

– Supports both 12- and 1.5-Mbps data rates (automatic generation of preamble token and data

rate configuration). Note that low-speed operation requires an external hub.

– Flexible data buffers with multiple buffers per frame

– Supports local loop back mode for diagnostics (12 Mbps only)

•

Serial peripheral interface (SPI)

— Supports master and slave modes

— Supports multiple-master operation on the same bus

•

Inter-integrated circuit (I2C) port

— Supports master and slave modes

— Supports a multiple-master environment

•

Time-slot assigner (TSA)

— Allows SCCs and SMCs to run in multiplexed and/or non-multiplexed operation

— Supports T1, CEPT, PCM highway, ISDN basic rate, ISDN primary rate, user defined
