Section 37 LCD Controller (LCDC)
37.4.2 Limits on the Resolution of Rotated Displays, Burst Length, and Connected
Memory (SDRAM)
This LCDC is capable of displaying a landscape-format image on a LCD module by rotating a
portrait format image for display by 90 degrees. Only the numbers of colors for each resolution are
supported as shown in table 37.5. The size of the SDRAM (the number of column address bits)
and its burst length are limited to read the SDRAM continuously.
The number of colors for display, SDRAM column addresses, and LCDC burst length are shown
table 37.5.
A monochromatic LCD module is necessary for the display of images in the above
monochromatic formats. A color LCD module is necessary for the display of images in the above
color formats.
