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 Device||Board Assembly Number|
Header Setup and Operation
For this header, you will need to set up jumper J2 and J3.
|J2||Open||Disable weak ICE/MCLR pull-up resistor|
|Short||Enable weak ICE/MCLR pull-up resistor|
|J3||Open||Disable power LED indicator|
|Short||Enable power LED indicator|
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.
The figure below 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 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.Figure: Dimensions – AC244028
