Parallel bus, command, etc. function
RAM contents not cleared; RAM data can be written.
V
When V = 0, the horizontal addressing is selected. The
data is written into the RAM as shown in Fig.6. When
V = 1, the vertical addressing is selected. The data is
written into the RAM as shown in Fig.7.
H
When H = 0 the commands ‘display control’, ‘set
Y address’ and ‘set X address’ can be performed, when
H = 1 the other commands can be executed. The
commands ‘write data’ and ‘function set’ can be executed
in both cases.
MX
When MX = 0, the display is written from left to right (X = 0
is on the left side, X = 100 is on the right side of the
display). When MX = 1 the display is written from right to
left (X = 0 is on the right side, X = 100 is on the left side of
the display).
MY
When MY = 1, the display is mirrored vertically.
Display Control
D
AND
E
The bits D and E select the display mode (see Table 2).
Set Y address of RAM
Y[3 : 0] defines the Y address vector address of the RAM.
Table 3
X-/Y-Address range
In bank 8 only the MSB is accessed.
Set X address of RAM
The X address points to the columns. The range of X is 0 to 101(65 hex).
Temperature Control
Due to the temperature dependency of the liquid crystals viscosity the LCD controlling voltage V
LCD
must be increased
with lower temperature to maintain optimal contrast. There are 4 different temperature coefficients available in the
