STM32F4 FSMC What is BusTurnAroundDuration and DataLatency

I am trying to setup my stm32f4-discovery board to work with an ili9341 TFT LCD. I have finally figured out how to use the FSMC to do this in 8080 parallel interface (thanks to lots of help and coffee).

I am now facing the challenge of setting up the timing, but I am unsure what BusTurnAroundDuration and DataLatency refers to, in setting up the FSMC timing. 

Any help would be greatly appreciated.

Below is an image of the desired timing for the ILI9341.

I am using the following setup timing for my stm32f4

However I am aware that I can use Timing.CLKDivision = 16 to slow the HCLK for my FSMC timings.
