3.2 Configuration Jumpers
The S5U13705B00C has six jumper blocks which configure various setting on the board.
The jumper positions for each function are shown below.
JP1 - IOVDD Selection
JP1 selects the IOVDD voltage for S1D13705.
When the jumper is in position 1-2, IOVDD is 3.3V. This settings must be used for a 3.3V
host CPU system.
When the jumper is in position 2-3, IOVDD is 5.0V. This setting must be used for a 5.0V
host CPU system.
Note
For PCI host, JP1 can be set in either position.
