DIP Switch
DIP switch DIP1A is a multi-purpose switch.
FPGA Mode: switches 1, 2, and 3 control the FPGA mode. The
supported configuration methods, Slave SelectMAP, Master BPI-Up, and
JTAG are selected by setting M[2:0] options.
CCLK_En: switch 4, controls the enable pin of the 48 MHz oscillator (U3).
When switch 4 is open/off U3 drives a 48 MHz clock onto the
FPGA_CCLK signal.
BPI_Flash: switch 5, is use to select between the Xilinx Platform Flash or
the Linear BPI Flash for the FPGA boot memory device.
SFP_Rate_Sel: switch 7 and 8 control the rate select to SFP modules 1
and 2 respectively.

Configuration Details
In JTAG mode switch5 On
selects FPGA access to BPI
Flash. Alternatively, set
switch5 Off for FPGA access to
the Platform Flash.
The supported configuration methods, Slave SelectMAP, Master BPI-Up, and
JTAG are selected by setting M[2:0] options (of the 8-position DIP switch) as
shown in the following table.

Power System Devices
The power to the XMC-6VLX is taken from the XMC P15 connector
VPWR_5/12 pins. The VPWR_5/12 power is the V in voltage to the four
LTM4602 devices U18, U19, U20, and U25. These LTM4602 devices output
+1.0V, +1.5V, +2.5V and +1.8V voltages. The +1.5 V supply is input to both
