the panel. Due to the SSD1908 Display Rotate feature, the end position Y may not be
a vertical position value (only true in 0° and 180° Display Rotate Mode). For further
information on defining the value of the End Position Y register, see Section 20
“Floating Window Mode”.
The value of register is also increased according to the display orientation. For 0° and
180° Display Rotate Mode, the end position Y is incremented by 1 line. For 90° and
270° Display Rotate Mode, the end position Y is incremented by y pixels where y is
relative to the current color depth. Refer to Table 7-14 : 32-bit Address Y Increments
for Various Color Depths.
Depending on the color depth, some of the higher bits in this register are unused
because the maximum vertical display height is 1024 pixels.
Note
These bits will not effective until the Floating Window Enable bit is set to 1 (REG[71h]
bit 4=1).
