Features
On-chip 16
× 16 multiply accumulate controller (MAC)
— One operation per clock (two-clock latency, one-clock blockage)
— MAC operates concurrently with other instructions
— FIR loop—Four clocks per four multiplies
Four baud rate generators
— Independent (can be connected to any SCC or SMC)
— Allow changes during operation
— Autobaud support option
Up to three serial communication controllers (SCCs) supporting the following protocols:
— Serial ATM capability on SCCs
— Optional UTOPIA port on SCC4
— Ethernet/IEEE Std 802.3 optional on the SCC(s) supporting full 10-Mbps operation
— HDLC/SDLC
— 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))
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
