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
2
Inter-integrated circuit (I C) 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
