Users who wish to use the ADC SPI interface must supply 5 VDC to P5, which provides power to the USB
circuit. By default, the EVM comes with the ADC configured in parallel mode. In order to use the SPI
interface to control the ADC modes of operation, users must move several jumpers.
• Move jumper JP11 to short positions 2–3, which places the ADC into serial operation mode.
• Move jumper JP8 to short positions 2–3, which allows the USB circuit to control SCLK.
• Move jumper JP9 to short positions 2–3, which allows the USB circuit to control SDATA.
• Move jumper JP10 to short positions 2–3, which allows the USB circuit to control SEN.
