Functional Description

2.1
The Version 2 ColdFire (CF2) core consists of two independent, decoupled pipeline structures to maximize
performance while minimizing core size. The instruction fetch pipeline (IFP) is a two-stage pipeline for
prefetching instructions. The prefetched instruction stream is then gated into the two-stage operand
execution pipeline (OEP), which decodes the instruction, fetches the required operands, and then executes
the required function.

Table 2. Digital and Analog Modules
The ATA block is an AT attachment host interface. Its main use is to
interface with IDE hard disc drives and ATAPI optical disc drives.
The six-channel ADC is based on the Sigma-Delta concept with 12-bit
resolution. Both the analog comparator and digital sections are integrated
in the MCF5251.
The audio interfaces connect to an internal bus that carries all audio data.
Each receiver places its received data on the audio bus and each
transmitter takes data from the audio bus for transmission.
The audio interface module provides the necessary input and output
features to receive and transmit digital audio signals over serial audio
interfaces (IIS/EIAJ) and over digital audio interfaces (IEC958).
The MCF5251 incorporates a ROM Bootloader, which enables booting
from UART, I2C, SPI, or IDE devices.
The FlexCan module is a full implementation of the Bosch CAN protocol
specification 2.0B, which supports both standard and extended message
frames.
Three programmable chip-select outputs (CS0/CS4, CS1, and CS2)
provide signals that enable glueless connection to external memory and
peripheral circuits.
There are four fully programmable DMA channels for quick data transfer.
The integrated eMAC unit provides a common set of DSP operations and
enhances the integer multiply instructions in the ColdFire architecture.
DMA and memory, peripherals, or other devices on the external bus.
The interface is Sony® Memory Stick®, SecureDigital, and Multi-Media
card compatible.
Note: The Sony Memory Interface does not support Sony MagicGate™.
