Freescale Semiconductor

— Binary synchronous communication (BISYNC)

— Totally transparent operation

•

Two full-duplex serial management controllers (SMCs) support the following protocols:

— GCI (ISDN interface) monitor and C/I channels

— UART

— Transparent operation

•

Serial peripheral interface (SPI) support for master or slave

•I2C bus controller

•

Time-slot assigner supports multiplexing of data from any of the SCCs, FCCs, SMCs, and MCCs

onto eight time-division multiplexed (TDM) interfaces. The time-slot assigner supports the

following TDM formats:

— T1/CEPT lines

—T3/E3

— Pulse code modulation (PCM) highway interface

— ISDN primary rate

— Freescale interchip digital link (IDL)

— General circuit interface (GCI)

— User-defined interfaces

•

Eight TC layers between the TDMs and FCC2 (MPC8280 only)

•

Eight independent baud rate generators (BRGs)

•

Four general-purpose 16-bit timers or two 32-bit timers

•

General-purpose parallel ports—sixteen parallel I/O lines with interrupt capability
