Display Memory Data Out Register (DMDO)
Read address = BxH.
Read/write access: read only.
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
NA
Character Address or Character Attribute byte to be read from 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 (see 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 to be interpreted as a Character Address byte, where
Bits 7–0 = CA[7:0] (see Figure 12)
followed by a Character Attribute byte, where
Bit 7 = 0
Bit 6 = Local Background Control bit, LBC (see Figure 24 and Table 4)
Bit 5 = Blink bit, BLK
Bit 4 = Invert bit, INV (see Figure 24)
Bit 3–0 = 0
The LBC, BLK, and INV bits are described in the Display Memory Mode register.
NA = Not applicable.
X = Don’t care.
Character Memory Data Out Register
(CMDO)
Read address = CxH.
Read/write access: read only.
To write to this register, the following conditions must
be met:
1) STAT[5] = 0, the character memory (NVM) is not
busy.
2) VM0[3] = 0, the OSD is disabled.
BIT
7, 6
5, 4

FUNCTION
Leftmost pixel. 00 = Black, 10 = White, 01 or 11 = Transparent (see Figure 11)
Left center pixel. 00 = Black, 10 = White, 01 or 11 = Transparent (see Figure 11)
Right center pixel. 00 = Black, 10 = White, 01 or 11 = Transparent (see Figure 11)
Rightmost pixel. 00 = Black, 10 = White, 01 or 11 = Transparent (see Figure 11)
NA = Not applicable.
X = Don’t care.
