Header Identification

The AC number is used for ordering the Processor Extension Pak which contains the debug header. However, this number is not on the header as the board may be used for multiple headers by inserting different -ICE/-ICD devices. To identify these headers, use the following information.

AC Number-ICE/-ICD DeviceBoard Assembly Number

Header Setup and Operation

For this header, you will need to set up jumpers J2 and J3.

J2OpenDisable weak ICE/MCLR pull-up resistor.
ShortEnable weak ICE/MCLR pull-up resistor.
J3OpenDisable power LED indicator.
ShortEnable power LED indicator.

Header Limitations

Sometimes a header device (-ICE/-ICD) has operational issues or errata. To determine if a device on a header has limitations, see your hardware tool documentation.

Header Dimensions

The accompanying image lists the dimensions for the debug header. Dimensions are design values in inches.

If the length and/or width of the debug header is too large of a footprint for the target board, consider using stand-offs, transition sockets, or other extenders in the header connection socket to raise the header above the target.
