Structs

Type Aliases

  • R
    Register SPI_MEM_CTRL2 reader
  • SPI_MEM_CS_HOLD_DELAY_R
    Field SPI_MEM_CS_HOLD_DELAY reader - These bits are used to set the minimum CS high time tSHSL between SPI burst transfer when accesses to flash. tSHSL is (SPI_MEM_CS_HOLD_DELAY[5:0] + 1) MSPI core clock cycles.
  • SPI_MEM_CS_HOLD_DELAY_W
    Field SPI_MEM_CS_HOLD_DELAY writer - These bits are used to set the minimum CS high time tSHSL between SPI burst transfer when accesses to flash. tSHSL is (SPI_MEM_CS_HOLD_DELAY[5:0] + 1) MSPI core clock cycles.
  • SPI_MEM_CS_HOLD_TIME_R
    Field SPI_MEM_CS_HOLD_TIME reader - SPI CS signal is delayed to inactive by SPI bus clock, this bits are combined with SPI_MEM_CS_HOLD bit.
  • SPI_MEM_CS_HOLD_TIME_W
    Field SPI_MEM_CS_HOLD_TIME writer - SPI CS signal is delayed to inactive by SPI bus clock, this bits are combined with SPI_MEM_CS_HOLD bit.
  • SPI_MEM_CS_SETUP_TIME_R
    Field SPI_MEM_CS_SETUP_TIME reader - (cycles-1) of prepare phase by SPI Bus clock, this bits are combined with SPI_MEM_CS_SETUP bit.
  • SPI_MEM_CS_SETUP_TIME_W
    Field SPI_MEM_CS_SETUP_TIME writer - (cycles-1) of prepare phase by SPI Bus clock, this bits are combined with SPI_MEM_CS_SETUP bit.
  • SPI_MEM_ECC_16TO18_BYTE_EN_R
    Field SPI_MEM_ECC_16TO18_BYTE_EN reader - Set this bit to enable SPI0 and SPI1 ECC 16 bytes data with 2 ECC bytes mode when accesses flash.
  • SPI_MEM_ECC_CS_HOLD_TIME_R
    Field SPI_MEM_ECC_CS_HOLD_TIME reader - SPI_MEM_CS_HOLD_TIME + SPI_MEM_ECC_CS_HOLD_TIME is the SPI0 CS hold cycle in ECC mode when accessed flash.
  • SPI_MEM_ECC_SKIP_PAGE_CORNER_R
    Field SPI_MEM_ECC_SKIP_PAGE_CORNER reader - 1: SPI0 and SPI1 skip page corner when accesses flash. 0: Not skip page corner when accesses flash.
  • SPI_MEM_SPLIT_TRANS_EN_R
    Field SPI_MEM_SPLIT_TRANS_EN reader - Set this bit to enable SPI0 split one AXI read flash transfer into two SPI transfers when one transfer will cross flash or EXT_RAM page corner, valid no matter whether there is an ECC region or not.
  • SPI_MEM_SYNC_RESET_W
    Field SPI_MEM_SYNC_RESET writer - The spi0_mst_st and spi0_slv_st will be reset.
  • W
    Register SPI_MEM_CTRL2 writer
