About i.MX 7Dual Enhanced LCD Interface (eLCDIF)

Hello,community

About connecting to peripheral devices with MPU interface (8080, 8 bits)
Timing charts are shown in Figures 13-13 and 13-14 of the i.MX 7 Dual Applications Processor Reference Manual.
TDSR and TDHR may be set with the LCDIF_TIMING register.
However, we were unable to find a description of standard values such as setup / hold time during READ and data confirmation time during WRITE.
If it is described in a parameter somewhere in the data sheet, can you tell me where it is specifically described?
There are W1 to W3 in the figure. Where is this time listed?

Best Regards,
Goto

I want to know the standard values of electrical characteristics for the following.
Are there any documents listed?
