When CG RAM addresses, bits C
5
to C
0
(binary), are set, the CG RAM is specified, until
the DD RAM address is set.
Write/read of the character pattern to and from the CPU begins with addresses, bits C
5
to C
0
, starting from CG RAM selection.
The execution time, when the OSC oscillation frequency is 270 kHz, is 37
m
s.
(8) DD RAM address setting
When the DD RAM addresses D
6
to D
0
(binary) are selected, the DD RAM is specified
until the DD RAM address is set.
Write/read of the character code to and from the CPU begins with addresses D
6
to D
0
starting from DD RAM selection.
In the 1-line display mode (N = H), however, D
6
to D
0
(binary) must be set to one of the
values among "00" to "4F" (hex.).
Likewise, in the 2-line mode, D
6
to D
0
(binary) must be set to one of the values among
"00" to "27" (hex.) or "40" to "67" (hex.).
When any value other than the above is input, it is impossible to make a normal write/
read of character codes to and from the DD RAM.
The execution time, when the OSC oscillation frequency is 270 kHz, is 37
m
s.
(9)DD RAM and CG RAM data write
When E
7
to E
0
(binary) codes are written to the DD RAM or CG RAM, the cursor and
display move as described in "(5) Cursor and display shift". The execution time, when
the OSC oscillation frequency is 270 kHz, is 37
m
s.
