Figure 7 Driver Output Control Instruction
CMS: Selects the output shift direction of a common driver. When CMS = 0, COM1 shifts to COM176.
When CMS = 1, COM176 shifts to COM1.
SGS: Selects the output shift direction of the segment driver. When SGS = 0, data are output SEG1 to
SEG396. When SGS = 1, data are output SEG396 to SEG1. When SGS = 0, SEG1 pin assigns the
color display to <R><G><B>. When SGS = 1, SEG396 pin assigns <R><G><B>. Re-write to the
RAM when intending to change the SGS bit.
NL4-0: 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.
