ADS8686S: can't drive ADS8686 through parallel interface

I am trying to use the STM32F407VGT6 to drive the ADS8686 through the parallel interface. The wiring is shown in the diagram.

My program, as shown below, is designed to read the data from the configuration registers. However, I am not getting any data:

#define ADC_BASE_ADDRESS ((uint32_t)0x60000000)
uint32_t usb_read_data=0;

/* USER CODE END FSMC_Init 0 */

FSMC_NORSRAM_TimingTypeDef Timing = {0};

/* USER CODE BEGIN FSMC_Init 1 */

/* USER CODE END FSMC_Init 1 */

/** Perform the NOR1 memory initialization sequence

hnor1.Instance = FSMC_NORSRAM_DEVICE;
hnor1.Extended = FSMC_NORSRAM_EXTENDED_DEVICE;
/* hnor1.Init */

hnor1.Init.ExtendedMode = FSMC_EXTENDED_MODE_DISABLE;
hnor1.Init.AsynchronousWait = FSMC_ASYNCHRONOUS_WAIT_DISABLE;
hnor1.Init.WriteBurst = FSMC_WRITE_BURST_DISABLE;
hnor1.Init.PageSize = FSMC_PAGE_SIZE_NONE;

Timing.DataLatency = 17;
Timing.AccessMode = FSMC_ACCESS_MODE_A;

if (HAL_NOR_Init(&hnor1, &Timing, NULL) != HAL_OK)
{

}

}
