Where is the right way to undersand NAND HAL configuring

Hello, dears!

I'm stucking around interfacing the NAND to STM32F746

The nand is (NAND512W3A2CN6)

Thus we have 512 bytes (0.5 kBytes) per Page

but in the HAL drivers description we can see:

PageSize - NAND memory page (without spare area) size measured in K. bytes

And more:

SpareAreaSize - NAND memory spare area size measured in K. bytes

but accordind the datasheet we have only 16 bytes (0.016 ?? of kilobyte?)

Where am I wrong? My configuration is below.

hnand1.Init.NandBank = FMC_NAND_BANK3;

hnand1.Init.Waitfeature = FMC_NAND_WAIT_FEATURE_ENABLE;

hnand1.Init.MemoryDataWidth = FMC_NAND_MEM_BUS_WIDTH_8;

hnand1.Init.EccComputation = FMC_NAND_ECC_ENABLE;

hnand1.Init.ECCPageSize = FMC_NAND_ECC_PAGE_SIZE_512BYTE;

hnand1.Init.TCLRSetupTime = 8;

hnand1.Init.TARSetupTime = 8;

/* hnand1.Info */

hnand1.Info.PageSize = 512;

hnand1.Info.SpareAreaSize = 16;

hnand1.Info.BlockSize = 32;

hnand1.Info.BlockNbr = 4096;

hnand1.Info.ZoneSize = 4096;

/* ComSpaceTiming */

ComSpaceTiming.SetupTime = 8;

ComSpaceTiming.WaitSetupTime = 12;

ComSpaceTiming.HoldSetupTime = 8;

ComSpaceTiming.HiZSetupTime = 8;

/* AttSpaceTiming */

AttSpaceTiming.SetupTime = 8;

AttSpaceTiming.WaitSetupTime = 12;

AttSpaceTiming.HoldSetupTime = 8;

AttSpaceTiming.HiZSetupTime = 8;

The Vendor ID and Product ID is reading proper by 0x20 and 0x76 following twice

HAL_NAND_Read_ID(&hnand1, &NAND_ID);

Thanks!
