1st Screen Driving Position (R14h)
2nd Screen Driving Position (R15h)
SS17–0: Specify the driving start position for the first screen in a line unit. The LCD driving starts from
the 'set value + 1' common driver.
SE17–0: Specify the driving end position for the first screen in a line unit. The LCD driving is
performed to the 'set value + 1' common driver. For instance, when SS17–10 = 07H and SE17–10 = 10H
are set, the LCD driving is performed from COM8 to COM17, and non-selection driving is performed for
COM1 to COM7, COM18, and others. Ensure that SS17–10 SE17–10 AFH. For details, see the
Screen-division Driving Function section.
SS27–0: Specify the driving start position for the second screen in a line unit. The LCD driving starts
from the 'set value + 1' common driver. The second screen is driven when SPT = 1.
SE27–0: Specify the driving end position for the second screen in a line unit. The LCD driving is
performed to the 'set value + 1' common driver. For instance, when SPT = 1, SS27–20 = 20H, and
SE27–20 = AFH are set, the LCD driving is performed from COM33 to COM80. Ensure that SS17–10
SE17–10 SS27–20 SE27–20 4FH. For details, see the Screen-division Driving Function section.
