Figure 4 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 a segment. When SGS = 0, SEG1 shifts to SEG396 and
<R><G><B> color is assigned from SEG1. When SGS = 1, SEG396 shifts to SEG1 and <R><G><B>
color is assigned from SEG396. Re-write to the RAM when intending to change the SGS bit.
Note: The CMS bit is for setting the common driver. Control according to the bit’s value is executed by
the common driver. For details, see the data sheet for the common driver.
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.
