Table 21-5. Pin Locations for Wiring ECP/EC to SPI Serial Flash
Software
The LatticeECP/EC FPGAs allow programming of the SPI Serial Flash via the ispJTAG port by using a small piece
of code to redirect the ispJTAG 4-wire interface to the SPI Flash 4-wire interface.
With the Soft SPI Interface installed, ispJTAG is free to read or write the SPI Serial Flash while the FPGA is execut-
ing user code. This allows the user to perform functions such as background configuration updates.
1. SPI is a four-wire interface; this table shows these wires plus the GPIO pin that needs to be wired to CCLK per Figure 21-2.
