Plane Selection Register (R17):
The plane
selection register (figure 46) controls general
operations of the HD66421. Each bit has its own
function as described below.
MON bit
MON = l: Monochrome display
MON = 0: 4-level gray scale display
DSEL bit
DESL = 1: Plane 1 is displayed
DESL = 0: Plane 0 is displayed
PSEL bit
PESL = 1: Access to plane 1 from CPU
PESL = 0: Access to plane 0 from CPU

Note
When you use the monochrome display, you have to initialize the x-address to even
number before access to display RAM. And you alway have to use even number.
