SPI_SMEM_AC writerType Definitions
Field
SPI_SMEM_CS_HOLD_DELAY reader - These bits are used to set the minimum CS high time tSHSL between SPI burst transfer when accesses to external RAM. tSHSL is (SPI_SMEM_CS_HOLD_DELAY[5:0] + 1) MSPI core clock cycles.Field
SPI_SMEM_CS_HOLD_DELAY writer - These bits are used to set the minimum CS high time tSHSL between SPI burst transfer when accesses to external RAM. tSHSL is (SPI_SMEM_CS_HOLD_DELAY[5:0] + 1) MSPI core clock cycles.Field
SPI_SMEM_CS_HOLD reader - Set this bit to keep SPI_CS low when MSPI is in DONE state.Field
SPI_SMEM_CS_HOLD_TIME reader - SPI Bus CS (SPI_CS) signal is delayed to inactive by SPI Bus clock (SPI_CLK), which is the SPI_CS hold time in non-ECC mode. These bits are combined with SPI_MEM_CS_HOLD bit.Field
SPI_SMEM_CS_HOLD_TIME writer - SPI Bus CS (SPI_CS) signal is delayed to inactive by SPI Bus clock (SPI_CLK), which is the SPI_CS hold time in non-ECC mode. These bits are combined with SPI_MEM_CS_HOLD bit.Field
SPI_SMEM_CS_HOLD writer - Set this bit to keep SPI_CS low when MSPI is in DONE state.Field
SPI_SMEM_CS_SETUP reader - Set this bit to keep SPI_CS low when MSPI is in PREP state.Field
SPI_SMEM_CS_SETUP_TIME reader - (cycles-1) of PREP phase by SPI_CLK, which is the SPI_CS setup time. These bits are combined with SPI_MEM_CS_SETUP bit.Field
SPI_SMEM_CS_SETUP_TIME writer - (cycles-1) of PREP phase by SPI_CLK, which is the SPI_CS setup time. These bits are combined with SPI_MEM_CS_SETUP bit.Field
SPI_SMEM_CS_SETUP writer - Set this bit to keep SPI_CS low when MSPI is in PREP state.Field
SPI_SMEM_ECC_16TO18_BYTE_EN reader - Set this bit to enable MSPI ECC 16 bytes data with 2 ECC bytes mode when accesses to external RAM.Field
SPI_SMEM_ECC_16TO18_BYTE_EN writer - Set this bit to enable MSPI ECC 16 bytes data with 2 ECC bytes mode when accesses to external RAM.Field
SPI_SMEM_ECC_CS_HOLD_TIME reader - SPI_SMEM_CS_HOLD_TIME + SPI_SMEM_ECC_CS_HOLD_TIME is the MSPI CS hold cycles in ECC mode when accesses to external RAM.Field
SPI_SMEM_ECC_CS_HOLD_TIME writer - SPI_SMEM_CS_HOLD_TIME + SPI_SMEM_ECC_CS_HOLD_TIME is the MSPI CS hold cycles in ECC mode when accesses to external RAM.Field
SPI_SMEM_ECC_ERR_INT_EN reader - Set this bit to calculate the error times of MSPI ECC read when accesses to external RAM.Field
SPI_SMEM_ECC_ERR_INT_EN writer - Set this bit to calculate the error times of MSPI ECC read when accesses to external RAM.Field
SPI_SMEM_ECC_SKIP_PAGE_CORNER reader - 1: MSPI skips page corner when accesses to external RAM. 0: Not skip page corner when accesses to external RAM.Field
SPI_SMEM_ECC_SKIP_PAGE_CORNER writer - 1: MSPI skips page corner when accesses to external RAM. 0: Not skip page corner when accesses to external RAM.
