AC244055
The AC number is used for ordering the Emulation Extension Pak (EEP) which contains the emulation header. However, this number is not on the header as the board may be used for multiple headers by inserting different -ME2 devices. To identify this header, use the following information:
| AC Number | -ME2 Device | Board Assembly Number |
| AC244055 | PIC16F1939-ME2 | 02-10039 |
Header Setup and Operation
For this header, you will need to select your device type using J5.
You can also enable the Power LED by using J3. J6 is not a jumper but a group of pins that you can use for trigger in and/or trigger out signals.
| Jumpers | Name | Setting | Function | Notes |
| J3 | LED Enable | Open | disable power LED indicator | —— |
| Short | enable power LED indicator | |||
| J5 | Emulation Selected | pins 1-2 | emulate 'F' variants (5.5 V MAX) | Note 1 |
| pins 2-3 | emulate 'LF' variants (3.6 V MAX!) | |||
| J6 | Trigger I/O | pin 1 | Ground | Note 2 |
| pin 2 | used for Trigger In | |||
| pin 3 | used for Trigger Out | |||
| Note 1: Do not change this setting when the header is powered. Power down first. Note 2: See the "Trigger In/Out" page. | ||||
Header Limitations and Errata
See the “Limitations” section in your debug tool online Help file for details.
For silicon errata, see the "-ME2 Silicon Errata" page.
Header Dimensions
The accompanying image lists the dimensions for the emulation header. Dimensions are design values in inches.
If the length and/or width of the emulation header is too large a footprint for the target board, consider using stand-offs, single in-line pins, transition sockets, or other extenders in the header connection socket to raise the header above the target.
