– Supports two independent PCMCIA sockets
– 8 memory or I/O windows supported
Communications Processor Module (CPM)
— Supports all functionality and performance of MPC860T
— RISC communications processor (CP)
— Communication-specic commands (for example, graceful stop transmit, close receive buffer
descriptor, RxBD)
— Up to 384 buffer descriptors
— Supports continuous mode transmission and reception on all serial channels
— Up to 8 Kbytes of dual-port RAM
— 10 serial DMA (SDMA) channels
— Three parallel I/O registers with open-drain capability
— Four baud rate generators
– Independent
– Baud rate changes allowed during operation
– Autobaud support option
— One SCC (serial communications controller)
– QMC multichannel protocol for processing 32 time-division-multiplexed channels
– Ethernet/IEEE 802.3u, supporting full 10-Mbps operation
– HDLC/SDLC (all channels supported at 2 Mbps)
