Initial value
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.

Initial value
This register sets the X coordinates of the display position of the L1 layer window. This register is
placed in two address spaces. The parenthesized address is the register address to maintain
compatibility with previous products. The same applies to L1WY, L1WW and L1WH.
