AC244035, AC244036
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 Device | Board Assembly Number |
| AC244035 | PIC16F1939-ICE | 02-02105 |
| AC244036 | PIC16LF1939-ICE |
Header Setup and Operation
For this header, you will need to set up the following jumpers.
| Jumper | Setting | Function |
| J2 | Open | Disable weak ICE/MCLR pull-up resistor. |
| Short | Enable weak ICE/MCLR pull-up resistor. This option keeps the target program running even after the tool has been disconnected from the header, i.e., the pin will not float high. | |
| J3 | Open | Disable power LED indicator. This option saves power. |
| Short | Enable power LED indicator. | |
| J4 | Open | Use only target capacitance for VCAP (on RA0 pin). |
| Short | Use both on-board and target capacitance for VCAP (on RA0 pin). | |
| J5 | Open | Use only target capacitance for VCAP (on RA5 pin). |
| Short | Use both on-board and target capacitance for VCAP (on RA5 pin). | |
| J6 | Open | Use only target capacitance for VCAP (on RA6 pin). |
| Short | Use both on-board and target capacitance for VCAP (on RA6 pin). |
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 figure 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.
