[Parameter P1]
MX0 Specifies the method of composing layered screens.
MX1 Selects the method of screen composition from OR, AND, Exclusive OR, and Prioritized OR as
listed in the table below. Because screens are composed in units of layers, different composition
methods cannot be used for individual screen blocks, even if a layer is divided into two screen
blocks.
Prioritized OR is the same as simple OR unless the flashing of individual screens is used in
combination with it.
