Vertical Scroll Control (R41h-R42h) (POR =0000h)
VL1[8:0]: Specify scroll length at the scroll display for vertical smooth scrolling. Any raster-row from the first to
can be scrolled for the number of the raster-row. After
raster-row. The display-start raster-row (VL1[8:0]) is valid when VLE1 = “1” or VLE2 = “1”. The raster-row display is
fixed when VLE[2:1] = “00”.
VL2[8:0]: Specify scroll length at the scroll display for vertical smooth scrolling at 2
row (VL2[8:0]) is valid when VLE1 = “1” and VLE2 = “1”.
Vertical RAM address position (R44h) (POR = EF00h)
VEA[7:0]/VSA[7:0]: Specify the start/end positions of the window address in the vertical direction by an address unit.
Data are written to the GDDRAM within the area determined by the addresses specified by VEA[7:0] and VSA[7:0].
These addresses must be set before the RAM write. In setting these bits, make sure that “00”h ≤ VSA[7:0] ≤ VEA[7:0] ≤
“EF”h.
Horizontal RAM address position (R45h-R46h)
HSA[8:0]/HEA[8:0]: Specify the start/end positions of the window address in the horizontal direction by an address unit.
Data are written to the GRAM within the area determined by the addresses specified by HEA[8:0] and HSA[8:0]. These
addresses must be set before the RAM write. In setting these bits, make sure that “00”h ≤ HSA[8:0] ≤ HEA[8:0] ≤
“13F”h.

SS1[8:0]: Specify the driving start position for the first screen in a line unit. The LCD driving starts from the set gate
driver, i.e. the first driving Gate is G1 if SS1[8:0] = 00H
SE1[8:0]: Specify the driving end position for the first screen in a line unit. The LCD driving is performed to the set gate
driver. For instance, when SS1[8:0] = “07”H and SE1[8:0] = “10”H are set, the LCD driving is performed from G7 to
G16, and non-selection driving is performed for G1 to G6, G17, and others. Ensure that SS1[8:0] ≤ SE1[8:0] ≤ EFH.
