6.5. SPI signal

The SPI signal is controlled by the FX2 microcontroller, but this signal could also be controlled by

FPGA.

The selection between the two clocks is done manually with a resistor.

Note: e2v doesn’t provide the SPI controller FPGA code.
Remove R93, R95, R97, R99 and R101 resistor and solder R94, R96, R98, R100 and R102 with a 0

Ω
