Field Documentation

baseAddr

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

protocol

uint32_t OSPI_Attrs::protocol

Protocol for OSPI reading/writing. 32 bit integer with byte0 -> data lines byte1 -> addr lines byte2 -> cmd lines byte3 -> STR/DTR (0 = STR, 1 = DTR)

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

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

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

readMode

uint32_t OSPI_Attrs::readMode

Select read mode DAC/INDAC

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

phyConfiguration

OSPI_PhyConfiguration OSPI_Attrs::phyConfiguration

OSPI PHY configuration params
