uint32_t OSPI_Attrs::baseAddr

Peripheral base address

◆ dataBaseAddr

uint32_t OSPI_Attrs::dataBaseAddr

Base address of the OSPI flash

◆ inputClkFreq

uint32_t OSPI_Attrs::inputClkFreq

Module input clock frequency

◆ intrNum

uint32_t OSPI_Attrs::intrNum

Peripheral interrupt number

◆ intrEnable

uint32_t OSPI_Attrs::intrEnable

Enable interrupt mode

◆ intrPriority

uint8_t OSPI_Attrs::intrPriority

Interrupt priority

◆ dtrEnable

uint32_t OSPI_Attrs::dtrEnable

Enable DTR

◆ dmaEnable

uint32_t OSPI_Attrs::dmaEnable

Enable DMA mode

◆ phyEnable

uint32_t OSPI_Attrs::phyEnable

Enable PHY mode

◆ dacEnable

uint32_t OSPI_Attrs::dacEnable

Enable DAC mode

◆ xferLines

uint32_t OSPI_Attrs::xferLines

Number of lines used for OSPI reading/writing

◆ frmFmt

uint32_t OSPI_Attrs::frmFmt

Ospi Frame Format

◆ devDelays

uint32_t OSPI_Attrs::devDelays[4]

OSPI device delays (CSSOT, CSEOT, CSDADS and CSDA delays)

◆ chipSelect

uint32_t OSPI_Attrs::chipSelect

Ospi Chip select number

◆ decChipSelect

uint32_t OSPI_Attrs::decChipSelect

Decoder Chip select number

◆ baudRateDiv

uint32_t OSPI_Attrs::baudRateDiv

Baud-rate divisor to derive DQS and other output clks

◆ dmaRestrictedRegions

const OSPI_AddrRegion* OSPI_Attrs::dmaRestrictedRegions

Pointer to array of OSPI_AddrRegion data structures filled by SysConfig. The array should be terminated by a { 0xFFFFFFFFU, 0U } entry. It is used while using DMA copy to check if the destination address is a region not accessible to DMA and switch to CPU copy
