◆ chipSelAddrSize

uint32_t GPMC_HwAttrs::chipSelAddrSize

Chip select address mask size

◆ waitPinNum

uint32_t GPMC_HwAttrs::waitPinNum

Wait pin number

◆ waitPinPol

uint32_t GPMC_HwAttrs::waitPinPol

Wait pin polarity

◆ timingParams

GPMC_timingParams GPMC_HwAttrs::timingParams

Structure holding the timing parameters for the GPMC instance.

◆ eccAlgo

GPMC_nandEccAlgo GPMC_HwAttrs::eccAlgo

◆ dmaRestrictedRegions

const GPMC_AddrRegion* GPMC_HwAttrs::dmaRestrictedRegions

Pointer to array of GPMC_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
