CK_DIS

1: spi clk out disable, 0: spi clk out enable. Can be configured in CONF state.
MASTER_CS_POL

In the master mode the bits are the polarity of spi cs line, the value is equivalent to spi_cs ^ SPI_MASTER_CS_POL. Can be configured in CONF state.
CLK_DATA_DTR_EN

1: SPI master DTR mode is applied to SPI clk, data and spi_dqs. 0: SPI master DTR mode is only applied to spi_dqs. This bit should be used with bit 17/18/19.
DATA_DTR_EN

1: SPI clk and data of SPI_DOUT and SPI_DIN state are in DTR mode, including master 1/2/4/8-bm. 0: SPI clk and data of SPI_DOUT and SPI_DIN state are in STR mode. Can be configured in CONF state.
ADDR_DTR_EN

1: SPI clk and data of SPI_SEND_ADDR state are in DTR mode, including master 1/2/4/8-bm. 0: SPI clk and data of SPI_SEND_ADDR state are in STR mode. Can be configured in CONF state.
CMD_DTR_EN

1: SPI clk and data of SPI_SEND_CMD state are in DTR mode, including master 1/2/4/8-bm. 0: SPI clk and data of SPI_SEND_CMD state are in STR mode. Can be configured in CONF state.
CD_DATA_SET

1: spi_cd = !SPI_CD_IDLE_EDGE when SPI_ST[3:0] is in SPI_DOUT or SPI_DIN state. 0: spi_cd = SPI_CD_IDLE_EDGE. Can be configured in CONF state.
CD_DUMMY_SET

1: spi_cd = !SPI_CD_IDLE_EDGE when SPI_ST[3:0] is in SPI_DUMMY state. 0: spi_cd = SPI_CD_IDLE_EDGE. Can be configured in CONF state.
CD_ADDR_SET

1: spi_cd = !SPI_CD_IDLE_EDGE when SPI_ST[3:0] is in SPI_SEND_ADDR state. 0: spi_cd = SPI_CD_IDLE_EDGE. Can be configured in CONF state.
SLAVE_CS_POL

spi slave input cs polarity select. 1: inv 0: not change. Can be configured in CONF state.
DQS_IDLE_EDGE

The default value of spi_dqs. Can be configured in CONF state.
CD_CMD_SET

1: spi_cd = !SPI_CD_IDLE_EDGE when SPI_ST[3:0] is in SPI_SEND_CMD state. 0: spi_cd = SPI_CD_IDLE_EDGE. Can be configured in CONF state.
CD_IDLE_EDGE

The default value of spi_cd. Can be configured in CONF state.
CK_IDLE_EDGE

1: spi clk line is high when idle 0: spi clk line is low when idle. Can be configured in CONF state.
CS_KEEP_ACTIVE

spi cs line keep low when the bit is set. Can be configured in CONF state.
QUAD_DIN_PIN_SWAP

1: spi quad input swap enable 0: spi quad input swap disable. Can be configured in CONF state.
