ister. It also adapts the memory-ordering format. Both big-endian and little-endian formats are supported. They are
configured in the MEMOR field of the LCDCON2 register.
The organization of the pixel data in the memory depends on the configuration and is shown in Table 45-5 and
Table 45-7.
Note: For a color depth of 24 bits per pixel there are two different formats supported: packed and unpacked. The packed for-
mat needs less memory but has some limitations when working in 2D addressing mode (See “2D Memory Addressing”
on page 1070.).
