Optional Debug Headers

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 this debug header, use the following information.
Header Setup and Operation
Both 28-pin and 44-pin device headers have jumpers related to the enabling or dis-
abling of the on-chip 2.5 volt voltage regulator. Please see the section entitled “On-Chip
Voltage Regulator” in the “dsPIC33F Family Reference Manual” (DS70165) for more
details.
Test points are available on this header to check the following:
Header Limitations
See the “Limitations” section in your debug tool online Help file for details.
Header Dimensions
The figures below list the dimensions for the debug headers. 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.
