<RDRSRC1[7:0]>) so as not to exceed 0x100 is required.
The BLEND processing of the LCDDA first breaks each data of two images into the
This broken down RGB data is each weighted on a scale of 256 (0x00/0x100 to

Weight assigned for Source 0
Weight assigned for Source 1
Thus, setting the sum of two images’ weights (Case of R setting: <RDRSRC0[7:0]>＋
Note: If added RGB data exceeds 0x100, correct BLEND cannot be achieved.
