Disable Other Devices on the SPI Bus to Avoid Contention

The SPI bus signals are shared by other devices on the board. It is vital that other devices

are disabled when the FPGA communicates with the AMP or ADC to avoid bus

contention.

Table 10-4

provides the signals and logic values required to disable the other

devices. Although the StrataFlash PROM is a parallel device, its least-significant data bit is

shared with the SPI_MISO signal. The Platform Flash PROM is only potentially enabled if

the FPGA is set up for Master Serial mode configuration.

Connecting Analog Inputs

Connect AC signals to VINA or VINB via a DC blocking capacitor.
