Table 48-13 shows the output se quence in the data output bus for single scan configurations. (In Dual Scan
Configuration, each panel data bus acts like in the equivalent single scan configuration.)

48.6.2.7 Shifter
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 DI STYPE, SCANMOD, and IFWIDTH fields of the LDCCON3
register.
The DISTYPE field selects between TFT, STN monochrome and STN color display. The SCANMODE 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).
For a more detailed description of the fields, see “LCD Controller (LCDC) User Interface” on page 1388.
For a more detailed description of the LCD Interface, see “LCD Interface” on page 1379.
