Window Address Function
The window address function enables writing display data sequentially in a window address area made in the internal
GDDRAM. The window address area is made by setting the horizontal address register (start: HSA7-0, end: HEA 7-0
bits) and the vertical address register (start: VSA8-0, end: VEA8-0 bits). The AM and ID[1:0] bits set the transition
direction of RAM address (either increment or decrement, horizontal or vertical, respectively). Setting these bits enables
the SSD1298 to write data including image data sequentially without taking the data wrap position into account. The
window address area must be made within the GDDRAM address map area.
Condition:
00h ≤ HSA[7:0] ≤ HEA[7:0] ≤ EFh
00h ≤ VSA[8:0] ≤ VEA[8:0] ≤ 13Fh
AM and ID[1:0] refer to R11h

Window address setting area:
HSA[7:0] = 3Bh; HEA[7:0] = B3h
VSA[8:0] = 8Bh; VEA[8:0] = B3h
AM = “0” and ID[1;]] = “11”
