Detailed Description

GPMC driver instance parameters.

GPMC Parameters are used to with the GPMC_open() call. Default values for these parameters are set using GPMC_Params_init().

If NULL is passed for the parameters, GPMC_open() uses default parameters.

Field Documentation

◆ gpmcDmaChIndex

int32_t GPMC_Params::gpmcDmaChIndex

Index of Channel used by GPMC DMA Driver. This index will be set by SysCfg according to the DMA driver chosen. The GPMC driver uses this index to do an GPMC_dmaOpen() inside the GPMC_open() if the DMA mode is enabled. device type, NAND or NOR like
