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
When the MPLAB ICD 2 is used with this header, you must use the Vpp Limiter
(AC164112).
