Motorola PowerQUICC II MPC8280 Series Reference Manual page 101

–Supports local loopback mode for diagnostics (12 Mbps only)
– Supports USB slave mode
–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
— Two serial management controllers (SMCs), identical to those of the MPC860
– Provide management for BRI devices as general circuit interface (GCI)
controllers in time- division-multiplexed (TDM) channels
– Transparent
– UART (low-speed operation)
— One serial peripheral interface identical to the MPC860 SPI
— One inter-integrated circuit (I
controller)
– Microwire compatible
– Multiple-master, single-master, and slave modes
— Up to eight TDM interfaces (four on the MPC8270)
– Supports two groups of four TDM channels for a total of eight TDMs (one
group of four on the MPC8270 and the MPC8275)
– 2,048 bytes of SI RAM
– Bit or byte resolution
– Independent transmit and receive routing, frame synchronization
– Supports T1, CEPT, T1/E1, T3/E3, pulse code modulation highway, ISDN
basic rate, ISDN primary rate, Motorola interchip digital link (IDL), general
circuit interface (GCI), and user-defined TDM serial interfaces
— Eight independent baud rate generators and 20 input clock pins for supplying
clocks to FCCs, SCCs, SMCs, and serial channels
— Four independent 16-bit timers that can be interconnected as two 32-bit timers
— Transmission convergence (TC) layer (MPC8280 only)
— Inverse multiplexing for ATM capabilities (IMA) (MPC8280 only). Supported
by eight TC layers between the TDMs and FCC2.
