Display Memory Data In Register (DMDI)
Write address = 07H, read address = 87H.
Read/write access: unrestricted.
To write to this register, the following condition must be
met:
DMM[2] = 0, the display memory is not in the process
of being cleared.
BIT
DEFAULT
FUNCTION
7–0
0000 0000
Character Address or Character Attribute byte to be stored in the display memory.
8-Bit Operation Mode (DMM[6] = 1)
If DMAH[1] = 0, the content is to be interpreted as a Character Address byte, where
Bits 7–0 = Character Address bits, CA[7:0] (Figure 12).
If DMAH[1] = 1, the content is to be interpreted as a Character Attribute byte where
Bit 7 = Local Background Control bit, LBC (Figure 24 and Table 4)
Bit 6 = Blink bit, BLK
Bit 5 = Invert bit, INV (see Figure 24)
Bit 4–0 = 0
(The LBC, BLK, and INV bits are described in the Display Memory Mode register.)
16-Bit Operation Mode (DMM[6] = 0)
The content is always interpreted as a Character Address byte where bits 7–0 =
CA[7:0] (Figure 12).
Auto-Increment Mode (DMM[0] = 1)
The character address CA[7:0] = FFH is reserved for use as an escape character that terminates
the auto-increment mode. Therefore, the character located at address FFH is not available for
writing to the display memory when in auto-increment mode. In all other modes, character FFH is
available.
