SPI0 flash DDR mode control register
Structs
- SPI0 flash DDR mode control register
Type Aliases
- Register
SPI_MEM_DDR
reader - Field
SPI_FMEM_CLK_DIFF_EN
reader - Set this bit to enable the differential SPI_CLK#. - Field
SPI_FMEM_CLK_DIFF_INV
reader - Set this bit to invert SPI_DIFF when accesses to flash. . - Field
SPI_FMEM_DDR_CMD_DIS
reader - the bit is used to disable dual edge in command phase when DDR mode. - Field
SPI_FMEM_DDR_DQS_LOOP
reader - 1: Do not need the input of SPI_DQS signal, SPI0 starts to receive data when spi0_slv_st is in SPI_MEM_DIN state. It is used when there is no SPI_DQS signal or SPI_DQS signal is not stable. 0: SPI0 starts to store data at the positive and negative edge of SPI_DQS. - Field
SPI_FMEM_DDR_EN
reader - 1: in DDR mode, 0 in SDR mode - Field
SPI_FMEM_DDR_RDAT_SWP
reader - Set the bit to reorder rx data of the word in spi DDR mode. - Field
SPI_FMEM_DDR_WDAT_SWP
reader - Set the bit to reorder tx data of the word in spi DDR mode. - Field
SPI_FMEM_DQS_CA_IN
reader - Set this bit to enable the input of SPI_DQS signal in SPI phases of CMD and ADDR. - Field
SPI_FMEM_HYPERBUS_CA
reader - Set this bit to enable HyperRAM address out when accesses to flash, which means ADDR_OUT[31:0] = {spi_usr_addr_value[19:4], 13’d0, spi_usr_addr_value[3:1]}. - Field
SPI_FMEM_HYPERBUS_DUMMY_2X
reader - Set this bit to enable the vary dummy function in SPI HyperBus mode, when SPI0 accesses flash or SPI1 accesses flash or sram. - Field
SPI_FMEM_OCTA_RAM_ADDR
reader - Set this bit to enable octa_ram address out when accesses to flash, which means ADDR_OUT[31:0] = {spi_usr_addr_value[25:4], 6’d0, spi_usr_addr_value[3:1], 1’b0}. - Field
SPI_FMEM_OUTMINBYTELEN
reader - It is the minimum output data length in the panda device. - Field
SPI_FMEM_RX_DDR_MSK_EN
reader - Set this bit to mask the first or the last byte in SPI0 ECC DDR read mode, when accesses to flash. - Field
SPI_FMEM_TX_DDR_MSK_EN
reader - Set this bit to mask the first or the last byte in SPI0 ECC DDR write mode, when accesses to flash. - Field
SPI_FMEM_USR_DDR_DQS_THD
reader - The delay number of data strobe which from memory based on SPI clock. - Field
SPI_FMEM_VAR_DUMMY
reader - Set the bit to enable variable dummy cycle in spi DDR mode.
