iMX7D :  How to determine eLCDIF timing ?

Dear community,
We have been developing our product with iMX7D.

I am planning to use LCDIF MPU mode.


I check an eLCDIF timing with Figure 13-13 "Timing in write mode of 6800 and 8080 protocols"
in the Reference Manual IMX7DRM (page 3639).


I know that LCD Interface Timing Register (LCDIFx_TIMING) is used for setting to CMD setup/hold and DATA setup/hold. But I can not find a register constituting the timing except LCDIFx_TIMING register.

 

[Question]
    So,
    Could you tell me how to determine the timing  as follows.
        1. timing width (W1 + W3)
        2. timing width (W2)
        3. timing point where LCD_CS signal is negated .
        4. timing width from negated LCD_CS signal to asserted LCD_CS signal .


Best Regards,
