4-5. RESET CONDITIONS
4-4-10. DDRAM OR CGRAM WRITE
4-4-11. DDRAM OR CGRAM READ
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
4) Entry Mode Set instruction bits:
5) Display On/Off Control instruction bits:
6) Function Set instruction bits:
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.
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.
to the non-shifted position.
I/D = 1: The AC increments after each DDRAM or CGRAM access. If S=1, the
S = 0:
D = 0: The display is off (display blank).
C = 0: The cursor is off.
B = 0: The blinking character function is disabled.
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.
