Hi all

 

I'm reading  IMX7DRM Rev. 0.1, 08/2016 and have question about eLCDIF in MPU interface.

 

Q1.

I want to transfer data and commands between the SoC via the eLCDIF in MPU interface as fast as possible.
I think the only way is to use higher DISPLAY_CLK.
Does someone have any idea ?

 

Q2

I want to immediately stop the transfer data.
I speculated that it'll stop when user set SFTRST field of LCDIFx_RLn register.
Am I correct ?
Also do you have any concern for that use case ?

 

Q2-1

If user can stop the data transfer with setting "1" to SFTRST, what happens to the output ports such as LCD command and data ?
Does the port keep Pull-up, Pull-down or Hi-Z ?

 

Q2-2

If Q2 is no, do you have any idea to stop the transfer data immediately ?
