Layer Composition Method (MX) bits [1:0]
These bits select the layered screen composition method, which can be OR, AND, or
Exclusive-OR. Since the screen composition is organized in layers and not by screen
blocks, when using a layer divided into two screen blocks, different composition methods
cannot be specified for the individual screen blocks.
L1: First layer (text or graphics). If text is selected, layer L3 cannot be used.
L2: Second layer (graphics only)
L3: Third layer (graphics only)
L1: Not flashing
L2: Flashing at 1 Hz
L3: Flashing at 2 Hz
