The functionality of the [IMM_DATA] field is shown in the following table. These commands can be applied to [CS_LOWER], [CS_UPPER], or both at the same time.
|Write data from [IMM_DATA]||0||Single byte to write||0||1||xx|
|Write [IMM_DATA] number of bytes data to TXFIFO||1||x||0||1||xx|
Read [IMM_DATA] number of bytes of data from RXFIFO
The maximum number of data bytes that can be transferred at one are 228 in DMA and PIO mode
|Defines the number of dummy cycles||1||Dummy QSPIx_CLK clock periods||0||0||xx|
|Chip select setup time||0||Measured in QSPI_REF_CLK clock periods||0||0||10|
|Chip select hold time||0||Measured in QSPI_REF_CLK clock periods||0||0||00|
