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.
