— The USB host controller has the following features:
Serial peripheral interface (SPI)
— Supports master and slave modes
— Supports multiple-master operation on the same bus
Inter-integrated circuit (I
— 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
— 1- or 8-bit resolution
— Allows independent transmit and receive routing, frame synchronization, and clocking
— Allows dynamic changes
— Can be internally connected to four serial channels (two SCCs and two SMCs)
Parallel interface port (PIP)
— Centronics interface support
— Supports fast connection between compatible ports on MPC885/MPC880 and other MPC8xx
PCMCIA interface
— Master (socket) interface, release 2.1-compliant
— Supports two independent PCMCIA sockets
— 8 memory or I/O windows supported
Debug interface
— Eight comparators: four operate on instruction address, two operate on data address, and two
— Supports conditions: = ≠ < >
— Each watchpoint can generate a break point internally.
Normal high and normal low power modes to conserve power
– Flexible data buffers with multiple buffers per frame
– Automatic retransmission upon transmit error
– 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
– Flexible data buffers with multiple buffers per frame
– Supports local loop back mode for diagnostics (12 Mbps only)
