- The core is designed to support
Winbond W25Q64BV memory. See the device data sheet for the command, address,
dummy bytes and data bytes required for each command and for the command,
address and data bits operating details.

This is a dedicated mode and supports only
Micron memories as SPI slave devices. The core supports most of the dual and standard Micron
memory SPI commands. Tje shows the core behavior.

for each command and for the command, address and data bits operating
details.
