● Rotation scroll screen map register

The rotation scroll screen map register specifies the start address of the pattern name table to be placed on each plane of the screen according to rotation parameter A and rotation parameter B. This is a write-only 16-bit register located at addresses 180050H to 18006EH. After turning on the power or resetting, the value will be cleared to 0, so be sure to set it.
