3.3.2 Adapter Boards

For new target designs, it is recommended that a 40-pin connector be used to directly interface with the MPLAB ICE 4 cable assembly, providing the best debugging experience. However for legacy target connections, adapter boards are available in a Adapter Pack (AC244140). Use of adapter boards will likely degrade debug performance.
