to change without notice.
3.1
Feature Overview
Version 2 ColdFire variable-length RISC processor core
— Static operation
— 32-bit address and data path on-chip
— Processor core runs at twice the bus frequency
— Sixteen general-purpose 32-bit data and address registers
— Implements the ColdFire Instruction Set Architecture, ISA_A, with extensions to support the
user stack pointer register, and 4 new instructions for improved bit processing
— Enhanced Multiply-Accumulate (EMAC) unit with four 48-bit accumulators to support 32-bit
signal processing algorithms
— Illegal instruction decode that allows for 68K emulation support
System debug support
— Real time trace for determining dynamic execution path
— Background debug mode (BDM) for in-circuit debugging
— Real time debug support, with two user-visible hardware breakpoint registers (PC and address
with optional data) that can be configured into a 1- or 2-level trigger
On-chip memories
— 8-Kbyte cache, configurable as instruction-only, data-only, or split I-/D-cache
— 64-Kbyte dual-ported SRAM on CPU internal bus, accessible by core and non-core bus
masters (e.g., DMA, FEC)
Fast Ethernet Controller (FEC)
— 10 BaseT capability, half duplex or full duplex
— 100 BaseT capability, half duplex or full duplex
— On-chip transmit and receive FIFOs
— Built-in dedicated DMA controller
— Memory-based flexible descriptor rings
— Media independent interface (MII) to external transceiver (PHY)
Three Universal Asynchronous Receiver Transmitters (UARTs)
— 16-bit divider for clock generation
— Interrupt control logic
— Maskable interrupts
— DMA support
