The core supports 24-bit addressing mode only.
Unsupported commands/features for this memory are:
•Fast read dual I/O continuous read mode.
•Fast read quad I/O continuous read mode.
•The command ABh is supported only for releasing the flash from power down or high performance mode. This command should not be used for reading the device ID. The command FFh (Mode bit Reset) is not supported, as this is recommended when using Dual/Quad mode feature.
Exceptional behavior for certain commands:
•Release power down/high performance mode (ABh): This command supports release power down/high performance mode or reading the device ID with a different combination of dummy bytes. The core only supports release power down/high performance-mode where only one command byte is required to be placed in the DTR. The other mode of the command is not supported, as there is another command (90h) to read the device ID.
