Header Identification
The header AC number is used for ordering the header. However, this number is not 
on the debug header, as the board is often used for multiple headers by inserting 
different ICE/ICD devices. To identify these debug headers, use the following 
information.
Header Setup and Operation – AC162062
For this header, there are no jumpers/switches. MPLAB IDE/MPLAB X IDE will use its 
selected device to choose the correct device to emulate.
Test points are available on this header to check the V
DD
, V
DDCORE
, and ground.
The PICDEM™ HPC Explorer Board is 5V, whereas the ICD device on the header is 
3.6V max. Therefore, modification to the demo board is necessary before the header 
can be used.
1.
Switch S3 should be set to ICE.
2.
Jumper J2 must be connected as shown in Figure 1 to modify the operating volt-
age. See demo board documentation for more information.
