Driver Output Control (R01h)
CMS: Selects the output shift direction of a common driver. When CMS = 0, COM1 shifts to COM80.
When CMS = 1, COM80 shifts to COM1.
SGS: Selects the output shift direction of a segment driver. When SGS = 0, SEG1 shifts to SEG312. When
SGS = 1, SEG312 shifts to SEG1. When SGS = 0, the SEG1 pin assigns the color display to R, G, or B.
When SGS = 1, the SEG312 pin assigns R, G, or B to the color display.
NL3–0: Specify the LCD drive duty ratio. The duty ratio can be adjusted for every eight raster-rows. GRAM
address mapping does not depend on the setting value of the drive duty ratio.
