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, the explanation of standard values such as setup / hold time during reading and data confirmation time during writing as in the following reference materials could not be found.
If it is described in any parameter in the data sheet, please tell me where it is specifically described.

Best Regards,
Goto

Hello,

Is the document you told me not the source code of the program?
I want a document that describes the timing and the time relationship.

Best Regards,
Goto
