1.1.4.4.9 DRV_NAND_FLASH_FeatureGet Function

C

bool DRV_NAND_FLASH_FeatureGet(const DRV_HANDLE handle, uint8_t *featureData, uint8_t featureDataSize, uint8_t featureAddress)

Summary

Read target specific features.

Description

This routine reads target specific features from NAND Flash.

Preconditions

The DRV_NAND_FLASH_Open() routine must have been called for the specified NAND Flash driver instance.

Parameters


Parameters	Description
handle	A valid open-instance handle, returned from the driver's open routine
featureData	Pointer to destination buffer into which sub-feature data to be placed from NAND Flash
featureDataSize	Total number of sub-feature data bytes to be read
featureAddress	Specific feature address to be send after command cycle

Returns

True - If specific feature is read successfully from the Flash.

False - If invalid handle.

Example

i.e. Read NAND Flash ECC controller if NAND Flash supports internal ECC controller
#define NAND_FLASH_TARGET_DISABLE_INTERNAL_ECC 0x90
uint8_t featureData[4];
DRV_HANDLE handle; // Returned from DRV_NAND_FLASH_Open

if (DRV_NAND_FLASH_FeatureGet(handle, featureData, sizeof(featureData), NAND_FLASH_TARGET_DISABLE_INTERNAL_ECC))
{
    // Feature data read successfully
}

Remarks

This routine will block for hardware access.
