This register sets the display origin address of the L1 layer.
For the direct color mode (16
bits/pixel), the lower 1 bit is “0”, and this register is treated as being aligned in 2 bytes.
Wraparound processing is not performed for the L1 layer, so the frame origin linear address and
display position (X coordinates, and Y coordinates) are not specified.
