6E - 5P49V60, 5P49V6965 and 5P49V6975 Evaluation Board User Guide
Board Power Supply
The voltage for each of the four V
DDO
pins can be selected with jumpers. In the 5-pin configuration, the center pin is connected to the
V
DDO
pin on the device. The four pins around it are connected to different power sources. A jumper connects the V
DDO
pin to a power
source of choice.
