Jumper Settings
Set up the board with the default jumper settings described in the table below. These settings are
required to run the pre-programmed design. It is recommended to confirm the dark shaded voltage
selection jumpers. Current measurement jumpers must be connected to permit current to flow. The
table order is from top to bottom and left to right on the board, to help you find them.

Device current can be measured by placing a multimeter between pin2 and pin 3 of JP10 (VCC_CORE).
The multimeter must be able to read μA current range for Flash*Freeze mode.
