1.1.2V2 Core Overview
The version 2 ColdFire processor core is comprised of two separate pipelines decoupled by an instruction buffer . The two-stage
instruction fetch pipeline (IFP) is responsible for instruction-address generation and instruction fetch. The instruction buffer is
a first-in-first-out (FIFO) buffer that holds prefetched instructions awaiting execution in the operand execution pipeline (OEP).
The OEP includes two pipeline stages. The first stage decodes instructions and selects operands (DSOC); the second stage
(AGEX) performs instruction execution and calculates operand effective addresses, if needed.
The V2 core implements the ColdFire instruction set architecture revision A+ with added support for a separate user stack
pointer register and four new instructions to assist in bit processing. Additionally, the MCF5213 core includes the
multiply-accumulate (MAC) unit for improved signal processing capabilities. The MAC implements a three-stage arithmetic
pipeline, optimized for 16×16 bit operations, with support for one 32-bit accumulator. Supported operands include 16- and
32-bit signed and unsigned integers, signed fractional operands, and a complete set of instructions to process these data types.
The MAC provides support for execution of DSP operations within the context of a single processor at a minimal hardware cost.
1.1.3Integrated Debug Module
The ColdFire processor core debug interface is provided to support system debugging with low-cost debug and emulator
development tools. Through a standard debug interface, access to debug information and real-time tracing capability is provided
on 100-lead packages. This allows the processor and system to be debugged at full speed without the need for costly in-circuit
emulators.
The on-chip breakpoint resources include a total of nine programmable 32-bit registers: an address and an address mask register,
a data and a data mask register, four PC registers, and one PC mask register. These registers can be accessed through the
dedicated debug serial communication channel or from the processor’s supervisor mode programming model. The breakpoint
registers can be configured to generate triggers by combining the address, data, and PC conditions in a variety of single- or
dual-level definitions. The trigger event can be programmed to generate a processor halt or initiate a debug interrupt exception.
The MCF5213 implements revision B+ of the ColdFire Debug Architecture.
The MCF5213’s interrupt servicing options during emulator mode allow real-time critical interrupt service routines to be
serviced while processing a debug interrupt event. This ensures the system continues to operate even during debugging.
To support program trace, the V2 debug module provides processor status (PST[3:0]) and debug data (DDATA [3:0]) ports .
These buses and the PSTCLK output provid e execu tion status, captured operand data, and branch target addresses defining
processor activity at the CPU’s clock rate. The MCF5213 includes a new debug signal, ALLPST . This signal is the logical AND
of the processor status (PST[3:0]) signals and is useful for detecting when the processor is in a halted state (PST[3:0] = 1111).
The full debug/trace interface is available only on the 100-pin packages. However, every product features the dedicated debug
serial communication channel (DSI, DSO, DSCLK) and the ALLPST signal.

1.1.4JTAG
The MCF5213 supports circuit board test strategies based on the Test T echnology Committee of IEEE and the Joint T est Action
Group (JTAG). The test logic includes a test access port (TAP) consisting of a 16-state controller, an instruction register, and
three test registers (a 1-bit bypass register, a 256-bit boundary-scan register, and a 32-bit ID register). The boundary scan register
links the device’s pins into one shift register. Test logic, implemented using static logic design, is independent of the device
system logic.
The MCF5213 implementation can:
•Perform boundary-scan operations to test circuit board electrical continuity
•Sample MCF5213 system pins during operation and transparently shift out the result in the boundary scan register
•Bypass the MCF5213 for a given circuit board test by effectively reducing the boundary-scan register to a single bit
•Disable the output drive to pins during circuit-board testing
•Drive output pins to stable levels
1.1.5On-Chip Memories
1.1.5.1SRAM
The dual-ported SRAM module provides a general-purpose 32-Kbyte memory block that the ColdFire core can access in a
single cycle. The location of the memory block can be set to any 32-Kbyte boundary within the 4-Gbyte address space. This
memory is ideal for storing critical code or data structures and for use as the system stack. Because the SRAM module is
physically connected to the processor's high-speed local bus, it can quickly service core-initiated accesses or
memory-referencing commands from the debug module.
The SRAM module is also accessible by the DMA. The dual-ported nature of the SRAM makes it ideal for implementing
applications with double-buffer schemes, where the processor and a DMA device operate in alternate regions of the SRAM to
maximize system performance.
1.1.5.2Flash Memory
The ColdFire flash module (CFM) is a non-volatile memory (NVM) module that connects to the processor’s high-speed local
bus. The CFM is constructed with four banks of 32-Kbyte×16-bit flash memory arrays to generate 256 Kbytes of 32-bit flash
memory. Th ese electrically erasable and programmable arrays serve as non-volatile program and data memory. The flash
memory is ideal for program and data storage for single-chip applications, allowing for field reprogramming without requiring
an external high voltage source. The CFM interfaces to the ColdFire core through an optimized read-only memory controller
that supports interleaved accesses from the 2-cycle flash memory arrays. A backdoor mapping of the flash memory is used for
all program, erase, and verify operations, as well as providing a read datapath for the DMA. Flash memory may also be
programmed via the EzPort, which is a serial flash memory programming interface that allows the flash memory to be read,
erased and programmed by an external controller in a format compatible with most SPI bus flash memory chips.
1.1.6Power Management
The MCF5213 incorporates several low-power modes of operation entered under program control and exited by several external
trigger events. An integrated power-on reset (POR) circuit monitors the input supply and forces an MCU reset as the supply
voltage rises. The low voltage detector (LVD) mon itors the supply voltage and is configurable to force a reset or interrupt
condition if it falls below the LVD trip point. The RAM standby switch provides power to RAM when the supply voltage to the
chip falls below the standby battery voltage.

MCF5213 Family Configurations
1.1.7FlexCAN
The FlexCAN module is a communication controller implementing version 2.0 of the CAN protocol parts A and B. The CAN
protocol can be used as an industrial control serial data bus, meeting the specific requirements of reliable operation in a harsh
EMI environment with high bandwidth. This instantiation of FlexCAN has 16 message buffers.
1.1.8UARTs
The MCF5213 has three full-duplex UARTs that function independently. The three UARTs can be clocked by the system bus
clock, eliminating the need for an external clock source. On smaller packages, the third UART is multiplexed with other digital
I/O functions.
1.1.9I2C Bus
The I2C bus is a two-wire, bidirectional serial bus that provides a simple, efficient method of data exchange and minimizes the
interconnection between devices. This bus is suitable for applications requiring occasional communications over a short
distance between many devices.
1.1.10QSPI
The queued serial peripheral interface (QSPI) provides a synchronous serial peripheral interface with queued transfer capability.
It allows up to 16 transfers to be queued at once, minimizing the need for CPU intervention between transfers.
1.1.11Fast ADC
The fast ADC consists of an eight-channel input select multiplexer and two independent sample and hold (S/H) circuits feeding
separate 12-bit ADCs. The two separate converters store their results in accessible buffers for further processing.
The ADC can be configured to perform a single scan and halt, a scan when triggered, or a programmed scan sequence repeatedly
until manually stopped.
The ADC can be configured for sequential or simultaneous conversion. When configured for sequential conversions, up to eight
channels can be sampled and stored in any order specified by the channel list register. Both ADCs may be required during a
scan, depending on the inputs to be sampled.
During a simultaneous conversion, both S/H circuits are used to capture two different channels at the same time. This
configuration requires that a single channel may not be sampled by both S/H circuits simultaneously.
Optional interrupts can be generated at the end of the scan sequence if a channel is out of range (measures below the low
threshold limit or above the high threshold limit set in the limit registers) or at several different zero crossing conditions.
1.1.12DMA Timers (DTIM0–DTIM3)
There are four independent, DMA transfer capable 32-bit timers (DTIM0, DTIM1, DTIM2, and DTIM3) on the MCF5213.
Each module incorporates a 32-bit timer with a separate register set for configuration and control. The timers can be configured
to operate from the system clock or from an external clock source using one of the DTINn signals. If the system clock is selected,
it can be divided by 16 or 1. The input clock is further divided by a user-programmable 8-bit prescaler that clocks the actual
timer counter register (TCRn). Each of these timers can be configured for input capture or reference (output) compare mode.
Timer events may optionally cause interrupt requests or DMA transfers.

Freescale Semiconductor10
MCF5213 Family Configurations
1.1.13General Purpose Timer (GPT)
The general purpose timer (GPT) is a four-channel timer module consisting of a 16-bit programmable counter driven by a
seven-stage programmable prescaler. Each of the four channels can be configured for input capture or output compare.
Additionally , channel th ree, can be configured as a pulse accumulator.
A timer overflow function allows software to extend the timing capability of the system beyond the 16-bit range of the counter.
The input capture and output compare functions allow simultaneous input waveform measurements and output waveform
generation. The input capture function can capture the time of a selected transition edge. The output compare function can
generate output waveforms and timer software delays. The 16-bit pulse accumulator can operate as a simple event counter or a
gated time accumulator.
1.1.14Periodic Interrupt Timers (PIT0 and PIT1)
The two periodic interrupt timers (PIT0 and PIT1) are 16-bit timers that provide interrupts at regular intervals with minimal
processor intervention. Each timer can count down from the value written in its PIT modulus register or it can be a free-running
down-counter.
1.1.15Pulse-Width Modulation (PWM) Timers
The MCF5213 has an 8-channel, 8-bit PWM timer. Each channel has a programmable period and duty cycle as well as a
dedicated counter. Each of the modulators can create independent continuous waveforms with software-selectable duty rates
from 0% to 100%. The PWM outputs have programmable polarity, and can be programmed as left aligned outputs or center
aligned outputs. For higher period and duty cycle resolution, each pair of adjacent channels ([7:6], [5:4], [3:2], and [1:0]) can
be concatenated to form a single 16-bit channel. The module can, therefore, be configured to support 8/0, 6/1, 4/2, 2/3, or 0/4
8-/16-bit channels.
1.1.16Software Watchdog Timer
The watchdog timer is a 32-bit timer that facilitates recovery from runaway code. The watchdog counter is a free-running
down-counter that generates a reset on underflow. To prevent a reset, software must periodically restart the countdown.
1.1.17Phase-Locked Loop (PLL)
The clock module contains a crystal oscillator, 8 MHz on-chip relaxation oscillator (OCO), phase-locked loop (PLL), reduced
frequency divider (RFD), low-power divider status/control registers, and control logic. To improve noise immunity, the PLL,
crystal oscillator, and relaxation oscillator have their own power supply inputs: VDDPLL and VSSPLL. All other circuits are
powered by the normal supply pins, VDD and VSS.
1.1.18Interrupt Controller (INTC)
The MCF5213 has a single interrupt controller that supports up to 63 interrupt sources. There are 56 programmable sources, 49
of which are assigned to unique peripheral interrupt requests. The remaining seven sources are unassigned and may be used for
software interrupt requests.
1.1.19DMA Controller
The direct memory access (DMA) controller provides an efficient way to move blocks of data with minimal processor
intervention. It has four channels that allow byte, word, longword, or 16-byte burst line transfers. These transfers are triggered
by software explicitly setting a DCRn[START] bit or by the occurrence of certain UART or DMA timer events.

Freescale Semiconductor11
MCF5213 Family Configurations
1.1.20Reset
The reset controller determines the source of reset, asserts the appropriate reset signals to the system, and keeps track of what
caused the last reset. There are seven sources of reset:
•External reset input
•Power-on reset (POR)
•Watchdog timer
•Phase locked-loop (PLL) loss of lock
•PLL loss of clock
•Software
•Low-voltage detector (LVD)
Control of the L VD and its associated reset and interrupt are managed by the reset controller . Other registers provide status flags
indicating the last source of reset and a control bit for software assertion of the RSTO
pin.
1.1.21GPIO
Nearly all pins on the MCF5213 have general purpose I/O capability and are grouped into 8-bit ports. Some ports do not use all
eight bits. Each port has registers that configure, monitor, and control the port pins.
