Freescale Semiconductor CodeWarrior™ USB TAP CWH-UTP-CF-HE CWH-UTP-CF-HE 信息指南

The CodeWarrior™ USB TAP host target

interface is a feature-packed, no nonsense

run-control tool that allows developers to save

precious development time during target

bring-up and debug providing visibility into

and control of Freescale™ on-chip debug

(OCD) features. The USB TAP integrates

seamlessly with the CodeWarrior integrated

development environment, giving the

developer a powerful tool for complex debug

tasks. The USB TAP features broad Freescale

processor support, complete run-control

functionality and flash programming for fast

downloads and convenient production testing.

Highlights
> High-speed USB 2.0 download

> Device is self-powered requiring no

external power supply

> Run-control visibility and control

> Flash memory programming

> Low voltage target support

> Fully integrated with CodeWarrior tools

and supports all CodeWarrior run-control
debug features

Detailed Features
> Gain optimal performance:

• Split-second single-step execution

• Fast code download to target,

depending on processor and target
design

• Control and debug your software

running in-target, with minimal intrusion
into target operation

> Use software or hardware breakpoints

> Crash-proof control of the target

processor

> Obtain and modify register contents 

> Display and modify memory

> Control instruction execution

> Run/stop/step/reset

> Available with a variety of connectors to

support a wide array of Freescale
processor families

> The combination of USB TAP and

CodeWarrior Development Studio
provides:

• Powerful C/C++ C/C++ source

correspondence

• Debug in ROM, RAM, and flash memory

Visibility — In conjunction with the

CodeWarrior debugger, the USB TAP

makes it possible for a developer to view

registers and the current state of target

memory. Program execution can be halted at

predefined states, and data for a particular

program state can be examined.

Control — The state of the target system

can be conveniently controlled by

downloading code, manually modifying

processor registers and memory, single-

stepping through the code, or setting

breakpoints.

Transparency — When using the USB TAP

it is virtually indistinguishable from non-

debug target execution.

For network or Ethernet debug capability,

the CodeWarrior Ethernet TAP run-control

product allows you to tap into the full

potential of your chosen Freescale

microprocessor and associated peripherals

providing you with an Ethernet-connected,

crash-proof development environment to

conduct processor system test, debug and

integration.
