7.3.1.4 Parallel 18-Bits Bus Interface for RAM Data Write (IM1, IM0=”11”)
Different display data formats are available for three colors depth supported by listed below.
(1). 18-bits data bus for 12-bits/pixel (RGB 4-4-4-bits input), 4K-colours, 3AH=”03h”
There is 1 pixel (3 sub-pixels) per 1 bytes
Note1. The data order is ad follows, MSB=D17, LSB=D0 and picture data is MSB=Bit 3, LSB=Bit 0 for Red, Green and Blue data.
Note 2.1-times transfer is used to transmit 1 pixel data with the 12-bits color depth information.
Note 3. ‘-‘ = Don't care - Can be set to VDDIO or DGND level
