In-target probe', or ITP is a device used in computer hardware and microprocessor design, to control a target microprocessor or similar ASIC

ASIC

ASIC may refer to:* Application-specific integrated circuit, an integrated circuit developed for a particular use, as opposed to a customised general-purpose device.* ASIC programming language, a dialect of BASIC...

 at the register level. It generally allows full control of the target device and allows the computer engineer access to individual registers, program counter, instructions within the device. It allows the processor to be single-stepped

Program animation

Program animation or Stepping refers to the very common debugging method of executing code one "line" at a time. The programmer may examine the state of the program, machine, and related data before and after execution of a particular line of code...

 or for breakpoints

Breakpoint

In software development, a breakpoint is an intentional stopping or pausing place in a program, put in place for debugging purposes. It is also sometimes simply referred to as a pause....

 to be set. Unlike an in-circuit emulator

In-circuit emulator

An in-circuit emulator is a hardware device used to debug the software of an embedded system. It was historically in the form of bond-out processor which has many internal signals brought out for the purpose of debugging...

 (ICE), an In-Target Probe uses the target device to execute, rather than substituting for the target device.
