both pixels, with the dithering pattern to apply to all of them being DP2_3 = “1101 1011 0110”.
Table 39-10
Dual Scan Configuration, each panel data bus acts like in the equivalent single scan
configuration.)
The FIFO, Serializer, Palette and Dithering modules process one pixel at a time in monochrome
mode and three sub-pixels at a time in color mode (R,G,B components). This module packs the
data according to the output interface. This interface can be programmed in the DISTYPE,
SCANMOD, and IFWIDTH fields of the LDCCON3 register.
The DISTYPE field selects between TFT, STN monochrome and STN color display. The SCAN-
MODE field selects between single and dual scan modes; in TFT mode, only single scan is
supported. The IFWIDTH field configures the width of the interface in STN mode: 4-bit (in single
scan mode only), 8-bit and 16-bit (in dual scan mode only).
