3.5 SETTING UP THE TARGET

Once the type of communication has been determined by inserting the corresponding

driver board into the emulator, the target must be set up to accommodate this, as well

as the type of target device to be used, i.e., regular or ICE.

Some devices have built-in debug circuitry. These “regular” devices may be used

directly by the emulator on the target.

Other devices have no built-in debug circuitry. For these devices, a special ICE device

(Device-ICE) is required, mounted on a header board. For more on header boards, see

the “Header Board Specification“ (DS51292).

3.5.1 Using Regular Devices

For regular devices, the emulator may be connected directly to the target board. The

device on the target board must have built-in debug circuitry in order for the MPLAB

REAL ICE in-circuit emulator to perform emulation with it. Consult the device data sheet

to see if the device has the needed debug circuitry, i.e., it should have a “Background

Debugger Enable” Configuration bit.

The target board must have a connector to accommodate to the communications

chosen for the emulator. For connection information, see Section 2.3.1 “Standard

Communication” or Section 2.3.2 “High-Speed Communication”.

3.5.2 Using ICE Devices and Header Boards

For ICE devices, an ICE header board is required. The header board contains the

hardware necessary to emulate a specific device or family of devices.

A transition socket is used with the ICE header to connect the header to the target

board. Transition sockets are available in various styles to allow a common header to

be connected to one of the supported surface mount package styles. For more

information on transition sockets, see the “Transition Socket Specification” (DS51194).

Header board layout will be different for standard or high-speed communications. For

connection information, see Section 2.3.1 “Standard Communication” or

Section 2.3.2 “High-Speed Communication”.

3.5.3 Powering the Target

If you have not already done so, connect the emulator pod to the target using the

appropriate cables for the driver board selected (see Section 3.4 “Selecting Target

Communications”). Then power the target.

Note: Some regular devices have ICE devices avaliable to provide dedicated

debug pins and (sometimes) memory.

Note: In the future, devices with circuitry that support ICD may be used, though

only standard debug, and not emulator debug, functions will be available.

Note: In the future, ICD header boards with ICD devices (Device-ICD) may be

used, though only standard debug, and not emulator debug, functions will

be available.

Note: The emulator cannot power the target.
