Freescale Semiconductor

Overview

— Auto-detection of 1x- and 4x-mode operation during port initialization

— Link initialization and synchronization

— Large and small size transport information field support selectable at initialization time

— 34-bit addressing

— Up to 256 bytes data payload

— All transaction flows and priorities

— Atomic set/clr/inc/dec for read-modify-write operations

— Generation of IO_READ_HOME and FLUSH with data for accessing cache-coherent data at

a remote memory system

— Receiver-controlled flow control

— Error detection, recovery, and time-out for packets and control symbols as required by the

RapidIO specification

— Register and register bit extensions as described in part VIII (Error Management) of the

RapidIO specification

— Hardware recovery only

— Register support is not required for software-mediated error recovery.

— Accept-all mode of operation for fail-over support

— Support for RapidIO error injection

— Internal LP-serial and application interface-level loopback modes

— Memory and PHY BIST for at-speed production test
