HEADERS FOR ICE DEVICES

Devices that have built-in debug circuitry do not require a header to use MPLAB ICD 2.

However, some pins and memory must be used to support the ICD function. Special

ICE versions offering additional pins, memory and emulator functions can be used to

provide superior debugging capabilities.

Currently-available headers and their associated ICE devices/supported devices are

shown in Table 2.

INSTALLATION

The MPLAB ICD 2 header is installed by following these steps:

1.

Set up the header board.

2.

Connect the header and MPLAB ICD 2.

3.

Connect the header and the target board.

Set Up the Header Board

To set up a header board:

1.

If the ICD device is not soldered onto the header, plug the ICD device into the

socket on the top of the header.

2.

Set any jumpers or switches to determine device functionality/selection as

specified in the following sections.

8/14-PIN HEADERS

For some headers, device peripherals need to be selected by setting jumper J1 to the

appropriate position. This will have the effect of selecting the device.
