3.19 LCD Data Process Accelerator (LCDDA)
an auxiliary function for display.

mirror-inverts display data function, as well as the function of superimposing two images
(αBlend, Picture in Picture, Superimposing font).
all use the Copy Back (write back) method. Image data is processed and the data is written into
the display Ram of the LCDC. Then the LCDC displays the processed data.
This microcontroller incorporates the LCD Data Process Accelerator function (LCDDA) as
The LCDDA supports the scaler function that scales up/down display data including the

Scale up: Can scale up to the magnification of 256/n: (n = 1 to 255).
Scale down: Can scale down to the magnification of 256/(n
(n = 1 to 255, m = 1 to 16).
90° / 180° / 270° / horizontal mirror reversal / vertical mirror reversal possible
Function of superimposing two images (Picture in Picture)
Superimposing (α-Blend) possible adjusting the gray level of two images
Font Draw function for Font Data represented in binary (monochrome)
Can scale up independently in horizontal/vertical directions.
Filtering by Bi-Cubic method is possible in scaled up images.
Can scale down independently in horizontal/vertical directions.
Filtering by Bi-Cubic method is possible in scaled down images.
