pub fn cmd_dis(
    &mut self
) -> BitWriterRaw<'_, u32, SPI_SMEM_DDR_SPEC, bool, BitM, 4>

Bit 4 - the bit is used to disable dual edge in CMD phase when ddr mode.

pub fn spi_smem_outminbytelen(
    &mut self
) -> FieldWriterRaw<'_, u32, SPI_SMEM_DDR_SPEC, u8, u8, Unsafe, 7, 5>

Bits 5:11 - It is the minimum output data length in the ddr psram.

pub fn spi_smem_tx_ddr_msk_en(
    &mut self
) -> BitWriterRaw<'_, u32, SPI_SMEM_DDR_SPEC, bool, BitM, 12>

Bit 12 - Set this bit to mask the first or the last byte in MSPI ECC DDR write mode, when accesses to external RAM.

pub fn spi_smem_rx_ddr_msk_en(
    &mut self
) -> BitWriterRaw<'_, u32, SPI_SMEM_DDR_SPEC, bool, BitM, 13>

Bit 13 - Set this bit to mask the first or the last byte in MSPI ECC DDR read mode, when accesses to external RAM.

pub fn spi_smem_usr_ddr_dqs_thd(
    &mut self
) -> FieldWriterRaw<'_, u32, SPI_SMEM_DDR_SPEC, u8, u8, Unsafe, 7, 14>

Bits 14:20 - The delay number of data strobe which from memory based on SPI_CLK.

pub fn dqs_loop(
    &mut self
) -> BitWriterRaw<'_, u32, SPI_SMEM_DDR_SPEC, bool, BitM, 21>

Bit 21 - 1: Use internal signal as data strobe, the strobe can not be delayed by input timing module. 0: Use input SPI_DQS signal from PAD as data strobe, the strobe can be delayed by input timing module

pub fn dqs_loop_mode(
    &mut self
) -> BitWriterRaw<'_, u32, SPI_SMEM_DDR_SPEC, bool, BitM, 22>

Bit 22 - When SPI_SMEM_DDR_DQS_LOOP and SPI_SMEM_DDR_EN are set, 1: Use internal SPI_CLK as data strobe. 0: Use internal ~SPI_CLK as data strobe. Otherwise this bit is not active.

pub fn spi_smem_clk_diff_en(
    &mut self
) -> BitWriterRaw<'_, u32, SPI_SMEM_DDR_SPEC, bool, BitM, 24>

Bit 24 - Set this bit to enable the differential SPI_CLK#.

pub fn spi_smem_hyperbus_mode(
    &mut self
) -> BitWriterRaw<'_, u32, SPI_SMEM_DDR_SPEC, bool, BitM, 25>

Bit 25 - Set this bit to enable the SPI HyperBus mode.

pub fn spi_smem_dqs_ca_in(
    &mut self
) -> BitWriterRaw<'_, u32, SPI_SMEM_DDR_SPEC, bool, BitM, 26>

Bit 26 - Set this bit to enable the input of SPI_DQS signal in SPI phases of CMD and ADDR.

pub fn spi_smem_hyperbus_dummy_2x(
    &mut self
) -> BitWriterRaw<'_, u32, SPI_SMEM_DDR_SPEC, bool, BitM, 27>

Bit 27 - Set this bit to enable the vary dummy function in SPI HyperBus mode, when SPI0 accesses to flash or SPI1 accesses flash or sram.

pub fn spi_smem_clk_diff_inv(
    &mut self
) -> BitWriterRaw<'_, u32, SPI_SMEM_DDR_SPEC, bool, BitM, 28>

Bit 28 - Set this bit to invert SPI_DIFF when accesses to external RAM. .

pub fn spi_smem_octa_ram_addr(
    &mut self
) -> BitWriterRaw<'_, u32, SPI_SMEM_DDR_SPEC, bool, BitM, 29>

Bit 29 - Set this bit to enable octa_ram address out when accesses to external RAM, which means ADDR_OUT[31:0] = {spi_usr_addr_value[25:4], 6’d0, spi_usr_addr_value[3:1], 1’b0}.

pub fn spi_smem_hyperbus_ca(
    &mut self
) -> BitWriterRaw<'_, u32, SPI_SMEM_DDR_SPEC, bool, BitM, 30>

Bit 30 - Set this bit to enable HyperRAM address out when accesses to external RAM, which means ADDR_OUT[31:0] = {spi_usr_addr_value[19:4], 13’d0, spi_usr_addr_value[3:1]}.

pub unsafe fn bits(&mut self, bits: u32) -> &mut W
