DDRAM OR CGRAM WRITE
RS
R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
1 0
Write data
This instruction writes the 8-bit data byte on DB7-DB0 into the DDRAM or CGRAM
location addressed by the AC. The most recent DDRAM or CGRAM Address Set
instruction determines whether the write is to DDRAM or CGRAM. This instruction
also increments or decrements the AC and shifts the display according to the I/D and S
bits set by the Entry Mode Set instruction.

DDRAM OR CGRAM READ
RS
R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
1 1
Read data
This instruction reads the 8-bit data byte from the DDRAM or CGRAM location
addressed by the AC on DB7-DB0. The most recent DDRAM or CGRAM Address Set
instruction determines whether the read is from DDRAM or CGRAM. This instruction
also increments or decrements the AC and shifts the display according to the I/D and S
bits set by the Entry Mode Set instruction. Before sending this instruction, a DDRAM
or CGRAM Address Set instruction should be executed to set the AC to the desired
DDRAM or CGRAM address to be read.
4-5.
RESET CONDITIONS
After a power-up reset, the module initializes to the following conditions:
1)
All DDRAM locations are set to 20H (character code for a space).
2)
The AC is set to DDRAM address 00H (i.e. sets cursor position to 00H).
3)
The
relationship between DDRAM addresses and character positions on the VFD is set
to the non-shifted position.
4)
Entry Mode Set instruction bits:
I/D = 1:
The AC increments after each DDRAM or CGRAM access. If S=1, the
information on the display shifts to the left by one character position after
each DDRAM write.
S = 0:
The display shift function is disabled.
5)
Display On/Off Control instruction bits:
D = 0:
The display is off (display blank).
C = 0:
The cursor is off.
B = 0:
The blinking character function
is disabled.
6)
Function Set instruction bits:
DL = 1:
Sets the data bus width for the parallel interface modes to 8-bit (DB7-DB0).
N = 1:
Number of display lines set to 2.
BR1,BR0=0,0:
Sets the luminance level to 100%.
