About 24bit LCD panel connection for i.MX25

Dear all,

 

We want to connect 24bit (RGB8bit) LCD panel to LCDC of i.MX25.

 

According to Table 33-3 in Reference Manual, it seems to be necessary to use 24 bpp AUS mode.

However, follows are explained in NOTE of Table 33-3.
"Need to add 24bpp paralled mode."

 

And, we found the following description.

In Figure 33-11, an LD [23:0] is listed.

LD18 to LD23 are multiplexed by other function pins.

 

We want to connect LCD in 24bit parallel, not AUS mode.
Does LCDC of i.MX25 support 24bit parallel connection?

 

If it is supported, would you teach the needed setting?
