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 DeviceBoard Assembly Number

Header Setup and Operation

For this header, you will need to select your device type using J5.

Header Damage.
Selecting the wrong type of device may cause device damage,
especially when Vdd is greater than 3.6V (with respect to Vss).

You can also enable the Power LED by using J3. J7, J8 and J9 are a group of pins that you can use for trigger in and/or trigger out signals.

Note 1: Do not change this setting when the header is powered. Power down first.

Header Limitations and Errata

See the “Limitations” section in your debug tool online Help file for details.

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.
