SYS3V3 Select (Header JP1)
The board attached to the PmodUSBUART can have its 3.3V rail powered by the header JP1. If jumper JP1 is set to
SYS, then the SYS3V3 pin is powered by the VCC outputted by the FTDI chip. If the board attached to the
PmodUSBUART is powered on its own, the jumper should be set to LCL.
