Figure 14 Memory Addresses in Monochrome Display Mode
Monochrome Display Mode
The HD66421 can control monochrome display.
This mode is set when MON is set to 1. Two plane
of display can be selected in this mode using two
bits data for gray scale. One plane can be selected
with PSEL bit for access from the CPU and with
DSEL bit for display. Theses two operations are
independent to each other, thus oneplane can be
rewritten while the other plane is
displayed. This means no flicker during being
rewritten. The address area is mapped to even
address from H'0 to H'26 in monochrome mode
and this address area is the same for both planes.
The plane 0 is accessed when PSEL is cleared to
0 and the plane 1 is selected when PSEL is set to
1. The plane 0 is displayed when DSEL is
cleared to 0 and the plane 1 is displayed when
DSEL is set to 1.
