Communications processor module (CPM)
— Supports all functionality and performance of MPC860MH
— RISC controller
— Communication specific commands (e.g., graceful stop transmit, close receive buffer
— Up to 384 buffer descriptors
— Supports continuous mode transmission and reception on all serial channels
— Up to 5 Kbytes of dual-port RAM
— Sixteen serial DMA (SDMA) channels
— Three parallel I/O registers with open-drain capability
Four baud rate generators
— Independent and can be connected to any serial communication controller (SCC) or serial
— Allow changes during operation
— Autobaud support option
Four SCCs (serial communication controllers)
— QMC microcode for protocol processing of 64 time-division multiplexed channels
— Ethernet/IEEE 802.3 on SCC1–4, supporting full 10-Mbps operation
— HDLC/SDLC™ (all channels supported at 2 Mbps)
— HDLC bus (implements an HDLC-based local area network (LAN))
— 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))
QUICC multichannel controller (QMC) microcode features
— Up to 64 independent communication channels on a single SCC
— Arbitrary mapping of 0–31 channels to any of 0–31 TDM time slots
— Supports either transparent or HDLC protocols for each channel
— Independent Tx/Rx buffer descriptors and event/interrupt reporting for each channel
— Running QMC microcode independently on multiple SCCs allows even more channels (for
Two serial management controllers (SMCs)
— UART
— Transparent
— General circuit interface (GCI) controller
descriptor, RxBD)
management controller (SMC)
example, 64 at 50-MHz system frequency)
