4.3.3 Default Jumper Configuration

The following table describes the default settings for each jumper on the EK-RA6M3. This includes copper
jumpers (Ex designation) and traditional pin jumpers (Jx designation.)
The Circuit Group for each jumper is the designation found in the board schematic (available in the Design
Package). Functional details for many of the listed jumpers may be found in sections associated with each
functional area of the kits.
