This section describes some examples on programming different data transfer lengths. Only the length related fields are mentioned.
When 128 bytes are read/written from the SPI flash, the generic FIFO configuration uses the values in Table: Generic FIFO Configuration for 128 Bytes.

When 1,000 bytes are read/written from the SPI flash, the generic FIFO configuration uses the values described by the options listed in Table: Generic FIFO Configuration for 1,000 Bytes.
When 1G bytes are read/written from the SPI flash, the generic FIFO configuration uses the values in Table: Generic FIFO Configuration for 1G Bytes.
