Features
— Three parallel I/O registers with open-drain capability
• Four baud-rate generators (BRGs)
— Independent (can be connected to any SCC or SMC)
— Allow changes during operation
— Autobaud support option
• Four serial communications controllers (SCCs)
— Ethernet/IEEE 802.3 optional on SCC1–4, supporting full 10-Mbps operation
(available only on specially programmed devices).
— HDLC/SDLC (all channels supported at 2 Mbps)

— Asynchronous HDLC to support PPP (point-to-point protocol)
— 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))
• Two SMCs (serial management channels)
— UART
— Transparent
— General circuit interface (GCI) controller
— Can be connected to the time-division multiplexed (TDM) channels
• One SPI (serial peripheral interface)
— Supports master and slave modes
— Supports multimaster operation on the same bus
• One I2C (inter-integrated circuit) port
— Supports master and slave modes
— Multiple-master environment support
• 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
— 1- or 8-bit resolution
