19.3.40 Plane n Start Position X Register (PnSPXR) (n = 1 to 6)
The plane n start position X registers (PnSPXR, n = 1 to 6) set the horizontal start position of
plane n in memory. The value is retained during power-on reset and manual reset.

Plane n Start Position X
The horizontal start position of plane n in
memory should be set in dot units.
Notes: 1. When YC is set by the PnDDF bit in
PnMR, an even value should be set.
2. Setting of values exceeding twice the
value of the plane n memory width X
register (PnMWX) is prohibited.
