I have a board with an RGB LCD connected to the pins corresponding to IPU1_DISP1_DATA00-23 and was using the SDK sample to code to get the display working. As I was going through I noticed these two different sets of pins.
What is the difference between the DISPn_DATAxx pins and the DIn_PINxx pins? Are they both utilized by the DI module in IPU, and how the two mechanisms chosen between?
Other than mentioning them as external pins to the IPU, I couldn't find any other reference to the DISPn_DATAxx pins.

Hi Adrian
DIn_PINxx pins are used for waveforms generators (producing sync signals)
and described in Table 68. Video Signal Cross-Reference i.MX6DQ Datasheet (rev.4, 7/2015)

Thanks, that helped my understanding. Thanks also for the link, that's a helpful document I had missed.
Looked at another question and got some of the answer I need... so the DIn_PINxx pins are the control lines, and the DISPn_DATAxx pins are the data lines!
Now am I right in assuming that DISP0 pins are connected to DI0 and DISP1 pins are connected to DI1?
yes, right.
