Freescale Semiconductor

Features

— HDLC bus (implements an HDLC-based local area network (LAN))

— Asynchronous HDLC to support point-to-point protocol (PPP)

— 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))

•

SMC (serial management channel)

— UART (low-speed operation)

— Transparent

•

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

controller, or both for testing purposes (loopback 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 loopback 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
