Table 14-3. Flash Programming Mode Pin Usage
Table 14-4. Memory Access Modes
External SPI Flash
When the Master SPI mode is used for configuration an external SPI Flash device is required to hold the configura-
tion data. The size of the bitstream and the required external SPI Flash is shown in Table 14-5.
