Floating Window End Position X Bits [9:0]
These bits determine the end position X of the floating window in relation to the origin
of the panel. Due to the SSD1908 Display Rotate feature, the end position X may not
be a horizontal position value (only true in 0° and 180° rotation). For further information
on defining the value of the End Position X register, see 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 X is incremented by x pixels where x is
relative to the current color depth. Refer to Table 7-13 : 32-bit Address X Increments
for Various Color Depths. For 90° and 270° Display Rotate Mode, the end position X is
incremented by 1 line.
Depending on the color depth, some of the higher bits in this register are unused
because the maximum horizontal display width is 1024 pixels.
Note
These bits will not effective until the Floating Window Enable bit is set to 1 (REG[71h]
bit 4=1).
