3.2.1 Header Identification
The header AC number is used for ordering the header. However, this number is not
on the emulation header, as the board is often used for multiple headers by inserting
different -ME2 devices. To identify this debug header, use the following information.
3.2.2 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.
Header -ME2 Device Board Assembly Number
AC244055 PIC16F1939-ME2 02-10039
CAUTION
Header Damage.
Selecting the wrong type of device may cause device damage,
especially when Vdd is greater than 3.6 V (with respect to Vss).
